Rally Tools

This documentation is currently WIP. Some sentences may randomly end and sections may be poorly organized.

This repository provides multiple helpful tools for working within the SDVI Rally environment. Some features are:

  • Preset uploader
  • Rule uploader
  • Automated deployer
  • Remote diff checker
  • Code sync checker

Installation

  • npm install -g rally-tools
  • rally (to check if it works)
  • rally config

Library usage

Most classes and functions are exposed through src/index.js. This means when you want to create a node plugin that uses this library, you should just use import {Preset, Rule, rallyFunctions, ...etc} from "rally-tools".

Development

  • Clone this repo
  • Run npm install
  • Run npm link to symlink the rally executable
  • Start npx rollup -cw or npm run watch in the background to automatically compile code
  • Test your changes
  • Commit your changes and run npm version <minor|patch> to increment the version

Config

Pass the --config option to read/write a different config file location. If including as a module, then you need to call

const rally = require("rally-tools");

rally.loadConfig(filename);
// OR
rally.setConfig({... config object here ...})

Options:

  • chalk: allow colored output.
  • restrictUAT: Only allow GET requests from UAT, not POST/PUT/etc.
  • api: Your api keys and urls
  • repodir: The directory of your repository. Should have 3 folders: silo-presets, silo-rules, silo-metadata.
  • defaultEnv: Your development environment, usually DEV.

Usage

To get started, run rally in any command prompt or terminal. If your config is setup, you will see environment data for each of your setup api keys. It will look like this:

Rally Tools vx.y.z CLI
   LOCAL: OK
   UAT: 200 OK
   DEV: Unconfigured
   PROD: 200 OK
   QA: 401 (Unauthorized)

Use rally help or rally help [command] to see all public commands and basic documentation.

rally stage

This command integrates with git to control and monitor deployed features.

The stage for an environment contains two main parts:

  • the list of currently deployed branches and their associated commits
  • the list of claim-ed presets

To begin using rally stage, you need to know the name of your "stage preset". This is the preset where all the current deployment data is stored. Each team working independently in rally should have their own stage preset. For example, the stage preset for the onramp team is called onramp. Additionally, each environment has its own stage preset, but stage presets should be named the same in each environment for consistency. To choose your target environment for any command, use the -e parameter, as in -e [env name]. Any command without -e will use your default environment. (To change default environment, run rally config defaultEnv).

Prerequisites

Viewing the stage (rally stage info) only requires a working install of rally-tools and a valid access token. Using other stage commands (edit, claim, pull) requires a few prerequisites:

  • git installed and in your $PATH
  • A up-to-date rally-tools style git repo folder
  • A clean working tree (use git stash if you don't want to commit)
  • A current branch of staging

The easiest way to check all these is to run git status. It should return the following text if your repo is ready:

$ git status
On branch staging
Your branch is up to date with 'origin/staging'.

nothing to commit, working tree clean

Before each run of rally stage edit, it is recommended that you run git fetch or git pull. This will prevent you from missing commits or branches that would otherwise be available. If your local repo is out of date rally stage edit will likely throw an error for "missing commits"

Basic Usage

To select your stage, run rally stage init [stage name]. This will bring up a short prompt asking for your name. This name is used for the rally stage claim command. Select yes to write the config to disk. The id of the stage preset and your name are saved in your rally config file (default ~/.rallyconfig). To check that this was successful, run rally stage info. You should not see an error.

rally stage info will list the stage status. The first section is the list of currently deployed branches and their commit hashes. The second section contains a list of presets claim-ed by developers. The commit hashes can be used in conjunction with git blame to find the branch associated with specific commits.


rally stage edit will allow you to edit the current stage. Running it with no arguments will produce a prompt with 4 options:

  • Add a branch
  • Remove a branch
  • Finalize stage
  • Quit

To navigate the menu, use arrow keys or typing to select your choice. Once selected, press enter to choose. Adding a branch will list all available remote branches. You cannot select local-only branches when adding. Use arrow keys or type to select, and enter to confirm your choice. Once you are done adding or removing branches from the stage, choose "Finalize." This will move you to the next step.

The finalize step will show the list of proposed changes as a diff. If everything looks good, press enter to continue to the deploy step.

Next, rally will use git to form a local version of your stage. This is where most errors will occur. Merge conflicts, missing commits, an out of date repo, or a claimed preset will all cancel your pending stage without applying any changes. If nothing goes wrong, you will see the output of a rally supply deploy set. This will list all the rules that will be uploaded as part of the stage. If this is OK, then hit enter. Note: This is the last prompt before rally begins deploying. Assuming there are no errors with the deployment, the uploaded code should be available for testing immediately. Don't be afraid afraid editing the stage: everything is reversible!


rally stage claim will allow you to claim or un-claim presets. Claiming a preset marks it as untouchable by rally stage. Any stage deployments attempting to use a claimed preset will fail. The intended use is for developers actively working on presets, or for hotfixes in the UI. Note that this is currently 1-directional: You can claim a preset that is already in the stage, but doing so will stop anyone from using rally stage edit.

The menu is similar to rally stage edit: use arrow keys/typing to select your option, and use enter to choose. Apply will upload your stage and apply your changes.


rally stage pull will load the current staged branches and apply them to a local branch. This lets you closely inspect the stage using your local editor or git commands.

rally stage Examples

Selecting the onramp stage file on the QA environment:

$ rally stage init onramp -e QA
Found stage target to init: P-QA-6354: onramp
? What is your name John
? Write config to disk? Yes
Created file /Users/jschmidt/.rallyconfig.

Stage edit example:

$ rally stage edit
Finished retreiving branches.
Stage loaded: onramp
? What do you want to do? Add a branch to the stage
? What branch do you want to add? changeA
? What do you want to do? Finalize stage
proposed changes
   changeB
   +changeA
? Prepare these branches for deployment? Yes
Required presets: 1
   P-LOCAL: Super Cool Preset
? Deploy now? Yes
Uploading preset Super Cool Preset to UAT: query type, (SdviEvaluate) ok, gmetadata 200, generate header, header ok, icode up 204, No tests. Done.

Stage edit via command line:

$ rally stage edit -a changeA -r changeB -r changeC
Finished retreiving branches.
Stage loaded: onramp
proposed changes
   changeD
  +changeA
  -changeB
  -changeC
...

rally stage Advanced Usage and Tips

While many of the commands for rally stage use interactive menus, they all have an option to be programmatically skipped with command line options.

  • -y will automatically skip all prompts asking for a yes or no answer.

  • rally stage edit accepts -a or --add to add a branch, and -r or --remove to remove a branch. Multiple branches can be supplied by using the argument multiple times.

  • rally preset claim currently does not support options to supply preset names, but that is coming soon.

If using this in a more complex script, --raw can be passed to some stage commands return json instead of printing text. For example:

$ rally stage info --raw
{
    "stage": [
        {
            "branch": "changeA",
            "commit": "9db12be45188ffb33954de3eccda10f0fe0aa00b"
        },
        {
            "branch": "changeB",
            "commit": "2028e92c5e397616380542aa6cc0505d85fb7074"
        }
    ],
    "claimedPresets": [
        {
            "name": "Airmaster_Finalize",
            "owner": "John"
        }
    ]
}

Combine that output with something like jq to easily manipulate it:

$ # List all the currently deployed branches
$ rally stage info --raw | jq -r .stage[].branch
changeA
changeB

rally preset

This command deals with preset actions such as creating, uploading, and downloading.

rally preset create can be used to create a preset. When run without arguments, a command line UI will be given. If you wish to script this, the flags --provider, --ext, and --name can be given.

The basic download usage is rally preset list, which lists all presets. Giving the --resolve flag will internal resolve the dynamic references in an object. You can then add these to the output using --attach. Ex. rally preset list -e PROD --resolve --attach

rally preset upload -e [env] -f [preset] can be used to upload a file to a remote env. You can specify multiple -f arguments to upload multiple files. If the - argument is given (rally preset upload -) then the files are read from stdin. For example: git diff HEAD..UAT --name-only | grep silo-presets | rally preset upload - will upload all changed files using git as the reference.

rally preset diff -f [preset] can be used to view the differences between a local file and a remote one. --command can be used to run a command other than diff. For example, rally preset diff -f abc.xyz --command vimdiff -e PROD would compare the local file abc.xyz to the remote version on prod using vimdiff. (make sure that zbc.xyz has a proper rally header/metadata or this will fail).

rally preset grab -f [preset] will attempt to download the metadata file for this asset. The --full argument can be given to also download the code, too.

rally rule

This command is similar to rally preset, but for Supply Chain Rules.

rally rule create can be used in the same fashion as rally preset create. To access the interactive rule creator, just run rally rule create with no arguments.

To see all rules, use rally rule list. --raw available.

rally provider

See all providers. rally provider list. --raw available.

rally asset

This command allows you to create and launch workflows on assets.

See rally help asset for a quick reference help menu.

The first part of the command will be getting an asset context. You can either:

  • Use an asset id (ex. discovery.sdvi.com/content/[id]).
    • add the --id [id] argument
    • ex. rally asset -e PROD --id 12345 launch ...
  • Use an asset name
    • add the --name [asset name] argument
    • ex. rally asset -e UAT --name 1232345_004_TCCS_123456_2 launch ...
  • Create a new asset
    • add the argument "create"
    • supply a name using --name
    • # will be replaces with a random number.
    • ex. rally asset create --name "TEST_FILE_#" -e UAT launch ...
  • Use an anonymous context. (not supported by all commands)
    • add the --anon argument
    • ex. rally asset --anon -e PROD launch ...

Once you have your target asset, you can run any of the following commands:

launch, launchEvaluate:

Launch a rule or evaluate on an asset. Works in anon contexts. Requires flag --job-name. Optional flag --init-data can supply data to the step in json format. It can load the json from a file, or receive it as a string, or read from stdin.

--priority is planned as a flag, but rally currently does not support dynamic priority on started jobs.

Launching as an evaluate means that no next steps will be ran.

ie.

  • from file: --init-data @filename.json
  • from text: --init-data '{"some": "json", "here": "yep"}
  • from stdin: --init-data -

Example: rally asset ... launch --job-name "00 john sandbox" --init-data '{"transcode": "XDCAM"}' rally asset ... launchEvaluate --job-name "00 john sandbox" --init-data '{"transcode": "XDCAM"}'

rally supply

This is probably the most complex command mechanically.

rally supply calc [starting rule] will create a supply chain object in memory. Then, using other flags you can do something with this chain.

  • --to [env] will copy the supply chain onto the env, creating new rules and presets as needed.
  • --check [env] will do a diff on each file in the chain to the remote given

rally supply make -f [files]

rally conifg

This command manages the "~/.rallyconfig" file, so that you don't need to edit it manually. rally config simply creates a new config walking through all the options.

rally config [key] gives the config interactor for a single key. rally config chalk would bring up y/n menu for color. rally config api would bring up the configuration for all all the environments, but rally config api.DEV would let you modify just the DEV credentials.

rally config --raw prints out the current config including configs changed by command line options

metadata:

This command prints metadata.

This will have two top level keys:

  • Workflow contains the workflow metadata
  • Metadata contains the supply chain metadata
  • AnalyzeInfo contains a random analyze artifact. Usually, this will be the main file, but it is highly recommend to no rely on this data being accurate.

The default print will use the internal node debug print. For full json, add the --raw argument.

Deployments

Deployments using this tool are based around supply chains. At their core, supply chains are simply a group of rally objects, where an object is either a rule, preset, or notification.

Although you can only deploy supply chains, there are many ways to construct the deployment you want. The first, recommended way is using rally supply make.

make takes a list of identifiers and constructs a supply chain. Identifiers come in two forms:

  • Remote types
    • These point to a unique preset or rule on some remote environment.
    • R-UAT-283 would mean rule id 283 on uat.
    • ex: P-UAT-283: Something python, R-DEV-617: Some rule
  • Local types
    • These point to a local file, relative to your repodir or absolute to your system
    • ./some/file/path
    • /user/someone/rally_repodir/some/file/path
    • Displayed as P-LOCAL: Something

You can take take list of local or remote identifiers to create a supply chain using rally supply make. Each file can be given by -f, or by using - to specify stdin. A shorthand for rally supply make - is rally @. This is the most used development command.

Lets say you edited these 3 objects in DEV.

$ cat > changes.txt
 P-DEV-283: NL - EST - Util Library
 P-DEV-285: NL P1000 - MP - Non Linear Media Preparation Workflow
 R-DEV-617: NL R1000 - MP - Non Linear Media Preparation Workflow

$ cat changes.txt | rally @
Reading from stdin
Required notifications: 
Required rules: 1
 R-DEV-617: NL R1000 - MP - Non Linear Media Preparation Workflow
Required presets: 2
 P-DEV-283: NL - EST - Util Library
 P-DEV-285: NL P1000 - MP - Non Linear Media Preparation Workflow

Rally tools by default will print out the current loaded supply chain object when using make. To do something else, you supply any number of post actions

There are 3 available post actions:

  • --to
    • This is the bread and butter deployment action. --to DEV would deploy the current supply chain onto DEV, adding or creating

Now you can treat this like any other supply chain, and deploy it. Remote to remote, or remote to local. However, this tool is built to integrate directly with git on your local filesystem.

If you edited those 3 files locally, then commited to git, you should be able to see the diff with the git command git diff HEAD HEAD^. We are only interested in the names, so lets get those.

Quick note: The shorthand for rally supply make - is rally @.

$ git diff HEAD HEAD^ --name-only
silo-presets/NL - EST - Util Library
silo-presets/NL P1000 - MP - Non Linear Media Preparation Workflow
silo-rules/NL R1000 - MP - Non Linear Media Preparation Workflow

$ #Passing those to make will produce a supply chain based on LOCAL
$ git diff HEAD HEAD^ --name-only | rally @
Reading from stdin
Required notifications: 
Required rules: 1
 R-LOCAL: NL R1000 - MP - Non Linear Media Preparation Workflow
Required presets: 2
 P-LOCAL: NL - EST - Util Library
 P-LOCAL: NL P1000 - MP - Non Linear Media Preparation Workflow

There is another way to do deployments that has been deprecated:

calc automatically generated links between rules and preset at a time where our git repos did not have all available presets. This is left here as a guide for older scripts, but may not work correctly on new versions:

rally supply calc [starting rule] [ending rule] does the heavy lifting of parsing rules, finding notifications, linking the presets, creating metadata, etc.

Using the E2 Supply chain as an example...

$ rally supply calc R1000 -e DEV
...
Calculating Supply chain...  R-DEV-617: NL R1000 - MP - Non Linear Media Preparation Workflow
Done!
Required notifications: 
N-21: SNS All - test
Required rules: 8
 R-DEV-617: NL R1000 - MP - Non Linear Media Preparation Workflow
 R-DEV-618: NL R2001 - MP - Make EST Media Articrafts by Split
 R-DEV-621: NL R3012 - MP - Make EST Media File using Media Convert
 R-DEV-622: NL R4001 - MP - Make EST Closed Caption File
 R-DEV-627: NL R3013 - MP - QC EST Media File Launcher
 R-DEV-623: NL R5001 - MP - Make EST Media ArtiCrafts by Join
 R-DEV-628: NL R3014 - MP - QC EST Media File using SimpleSDVIQC
 R-DEV-623: NL R5001 - MP - Make EST Media ArtiCrafts by Join
Required presets: 10
 P-DEV-285: NL P1000 - MP - Non Linear Media Preparation Workflow
  P-DEV-18: Fail
 P-DEV-283: NL - EST - Util Library
 P-DEV-284: NL - MP - Util  Library
 P-DEV-286: NL P2001 - MP - Make EST Media Articrafts by Split
 P-DEV-289: NL P3012 - MP - Make EST Media File using MediaConvert
 P-DEV-290: NL P4001 - MP - Make EST Closed Caption File
 P-DEV-306: NL P3013 - MP - QC EST Media File Launcher
 P-DEV-291: NL P5001 - MP - Make EST Media ArtiCrafts by Join
 P-DEV-307: NL P3014 - MP - QC EST Media File using SimpleSDVIQC

This internally creates a supply chain object, which we can then apply an action to.

An example action is sync, which is given by the --to arg. rally supply calc R1000 -e DEV --to LOCAL would sync this supply chain (based on DEV) to LOCAL. In order to move it to a protected envornment, add --no-protect.

However, calc is limited by the fact that it is very rigid. Its best use is the inital setup of an environment, or to mass move supply chains. To fix this, lets move to rally supply make

To give a generic approach, in order to deploy all the changes between 2 commits, run git diff featureCommit baseCommit --name-only | rally @ --to DEV. rally is currently stateless: It does not remember what is deployed, who deployed it or when. All this should be tracked through git. Therefore, tagging releases or using a release branch would allow for basic version control.

Automated deployments

Automated deployments should be constructed telling rally tools the list of changed presets and rules. Silo constants, notification presets, and silo metadata should be changed manually before an automatic deploy, as these can not be stored in source control.

For example, if the previous deployment to prod was the tagged commit v1.2.3, and the new deployment will be version v2.0.0, then the deployment script will be git diff v2.0.0 v1.2.3 --name-only | rally @ --to PROD --no-protect

This will need to be run on a computer with a .rallyconfig in the home directory, otherwise the config should be given by the --config flag to the rally command.

Examples

Heres some other examples of common usage:

Upload a preset rally preset upload -e DEV -f "~/ORP/silo-presets/Audio Metadata Conditioner.py"

Look at all ffmpeg jobs rally rule list -e DEV --resolve --attach | grep ffmpeg

Clone some ffmpeg jobs you want to edit (vipe optional) rally rule list -e DEV --resolve --attach | grep ffmpeg | vipe | rally supply make - --to LOCAL

Create a new supply chain and print it rally supply calc ORHIVE

Header Parsing

There are two types of headers in standard rally usage. The first is the rally docstring. It looks like this:

'''
name: (Name of the preset as it exists on the silo)
autotest: (Name of movie for testing purposes)
autotest: (Name of movie, supports and arbitrary nubmer)
autotest: (Name of movie, ....)
autotest: id: (id of movie to test)
'''

This docstring contains into about what the name of the preset on the enviornment should be and what tests should be run on upload. The docstring is parsed by rally tools on upload. It does not need to be at the top of the file, and can use either single-quotes ', double-qoutes ". Using # for the docstring is discouraged.

This header is automatically generated when using rally preset create.

- can be used to disable autotests temporarily.

# name: ok
# autotest: ok
// name: also works
-autotest: will not run
-- autotest: this will run

The second type of header is the deployment info header. On any upload from rally tools, we will look for a file named bin/header.sh. This will be inserted at the start of each python upload using info about deployment time, git info, and uploader name.

On any automatic download, this header will be automatically stripped. You should never see this type of header in git locally. Here is an example header format:

# Built On: Wed 2020/01/02 12:53:13pm
# Author: John Schmidt <john@john2143.com>
# Tag: releases/23
# Build: 
# Version: .
# Branch: staging
# Commit: 20ab14bc6d16a19e60962efbe213a33fc21bafb7
# Local File: YEP/silo-presets/COC.py
###############################################################

The deployment info header can be read with rally preset info. It is used like a rally preset upload command, where you supply the local file to be read from multiple environments.

It will print dependencies and then show all the build info. Heres an example output:

$ rally preset info --file "YEP/silo-presets/COC.py" --e UAT,PROD

Atom integration

Rally tools now supports a basic amount of atom integration including testing, uploading, downloading, and rule managment. Two plugins are used for this: process-pallete, and optionally, file-watcher. Please see the file process-pallete.json in jderby/ONRAMP_WORKFLOW_PYTHON.

This should be copied into your base directory (same level as the silo-* folders)

This is still early in testing and does not support features like diffs and inline live test results

Vim integration

Anyone else use vim? Just me? Heres my config:

all the file arguments are ^R% where ^R is the CTRL-R sequence (register-insert-command mode). Use CTRL-V in insert mode to enter insert-escape mode, then press CTRL-R to type that sequence.

Troubleshooting

Cannot acclimatize shelled preset

Solution: Create the preset on the remote enviornment manually, or run rally preset create

Under normal usage, presets will have an associated metadata file saved. This contains information like its provider type, input and output settings, or timestamps. Preset#acclimatize attempts to take this data from a generic format into an environment specific format so that it can be accuractly created when uploading. A file without any metadata is marked as "Shelled" and given some dummy data while limiting functionality. This functionality includes updating the code of a preset, or viewing the metadata of an enviornment.

CLI Aborted: Protected enviorment

Solution: Add the --no-protect flag, or run rally config restrictUAT to unprotect UAT (if the error is on UAT).

Protected enviorments cannot recieve anything but get requests, so any kind of POST/PUT/PATCH will fail with this error. Internally, --no-protect is sets the --protect flag to false instead of true, which in turn sets the configObject.dangerModify flag to true. So if you really wish, you could add "dangerModify": true, to your config to allow unrestricted UAT/PROD posts, then use the --protect flag when you want safe calls.

API Error

Sometimes, the rally API simply wont work. Verify that all endpoints are active by running rally. Under normal circumstances, they should return a 2xx response.

If that is ok, read the data that is returned by the API to see if it is a fixable error: ex. 401 Unauthorized probably means that you have a bad API key, so run rally config api or rally config api.UAT.
