go-fastly-cli

Note: this project was hacked together many years ago to solve a specific problem I had. It works perfectly for me but if you're reviewing the code to see how it is put together, then just remember that A.) the code quality isn't as good as it probably could be, and B.) the code design equally could be greatly improved. Otherwise have fun with it.

CLI tool for:

  • Uploading local VCL to Fastly.
  • Diffing local VCL with remote Fastly VCL.
  • Listing remote Fastly VCL files.
  • Deleting remote Fastly VCL files.
  • Creating, Activating and Validating Fastly service versions.

This tool is an abstraction layer built on top of "go-fastly".

Install

go get github.com/integralist/go-fastly-cli

GOOS=darwin GOARCH=386 go build fastly.go

Usage

fastcli <flags> [diff <options>]
fastcli <flags> [upload <options>]
fastcli <flags> [list <options>]
fastcli <flags> [delete <options>]

Flags:

fastcli -help

  -activate string
        specify Fastly service version to activate
  -debug
        show any debug logs and subcommand specific information
  -dir string
        the directory where your vcl files are located
  -help, -h
        show available flags
  -match string
        regex for matching vcl directories (fallback: VCL_MATCH_PATH)
  -service string
        your Fastly service id (fallback: FASTLY_SERVICE_ID) 
  -settings string
        get settings for the specified Fastly service version (try: 'latest')
  -skip string
        regex for skipping vcl directories (will also try: VCL_SKIP_PATH) 
  -status string
        get status for the specified Fastly service version (try: 'latest')
  -token string
        your fastly api token (fallback: FASTLY_API_TOKEN) 
  -validate string
        specify Fastly service version to validate
  -version
        show application version

Diff Options:

fastcli diff -help

Usage of diff:
  -version string
        specify Fastly service version to verify against

Upload Options:

fastcli upload -help

Usage of upload:
  -clone string
        specify a Fastly service version to clone from (files will upload to it)
  -latest
        use latest Fastly service version to upload to (presumes not activated)
  -version string
        specify non-active Fastly service version to upload to

List Options:

fastcli list -help

Usage of list:
  -version string
        specify Fastly service version to list VCL files from

Delete Options:

fastcli delete -help

Usage of delete:
  -name string
        specify VCL filename to delete
  -version string
        specify Fastly service version to delete VCL files from

Environment Variables

The use of environment variables help to reduce the amount of flags required by the fastly CLI tool.

For example, I always diff against a 'stage' service in our Fastly account and so I don't want to have to put in the same credentials all the time.

Below is a list of environment variables this tool supports:

  • FASTLY_API_TOKEN (-token)
  • FASTLY_SERVICE_ID (-service)
  • VCL_DIRECTORY (-dir)
  • VCL_MATCH_PATH (-match)
  • VCL_SKIP_PATH (-skip)

Use the relevant CLI flags to override these values

You can quickly view the relevant environment variables in your current shell using the following bash command:

env | sort | grep -iE '(vcl|fastly)'

FASTLY_API_TOKEN=123
FASTLY_SERVICE_ID=456
VCL_DIRECTORY=/Users/integralist/code/organization/cdn
VCL_MATCH_PATH=stage|www
VCL_SKIP_PATH=utils

In the above output we can see that the files I'll upload will be only those that are located in either a stage or www sub directory of my repository (which is found at VCL_DIRECTORY). I'll also skip uploading any files stored in the utils sub directory.

Examples

Note: all examples presume FASTLY_API_TOKEN/FASTLY_SERVICE_ID env vars set

# view status for the latest service version
fastcli -status latest

# view status for the specified service version
fastcli -status 123

# view settings for the latest service version
fastcli -settings latest

# view settings for the specified service version
fastcli -settings 123

# validate specified service version
fastcli -validate 123

# activate specified service version
fastcli -activate 123

# view latest version of remote service vcl files
fastcli list

# view version 123 of remote service vcl files
fastcli list -version 123

# delete specified vcl file from latest version of remote service
fastcli delete -name test_file

# delete specified vcl file from specific version of remote service
fastcli delete -name test_file -version 123

# diff local vcl files against the lastest remote versions
fastcli diff

# diff local vcl files against the specific remote versions
fastcli diff -version 123

# enable debug mode
# this will mean debug logs are displayed
# for 'diff' subcommand: also display per file diff
fastcli -debug diff -version 123

# upload local files to remote service version
fastcli upload -version 123

# token and service explicitly set to override env vars
fastcli -service xxx -token xxx upload -version 123

# modify VCL directory temporarily + use different token/service id
VCL_MATCH_PATH=foo fastcli -token $FASTLY_API_TOKEN_FOO -service $FASTLY_SERVICE_ID_FOO diff

# clone specified service version and upload local files to it
fastcli upload -clone 123

# upload local files to the latest remote service version
fastcli upload -latest

# clone latest service version available and upload local files to it
fastcli upload

Makefile

To compile binaries for multiple OS architectures:

make compile

To start up a dockerized development environment (inc. Vim):

make dev

To install a local binary for testing (darwin):

make install

To remove all compiled binaries, vim files and containers:

make clean

TODO

  • Ability to purge URLs (both individual and those associated by surrogate keys)
  • Ability to 'dry run' a command (to see what files are affected, e.g. what files will be uploaded and where)
  • Ability to diff two remote services (not just local against a remote)
  • Ability to upload individual files (not just pattern matched list of files)
  • Ability to display all available services (along with their ID)
  • Better diffing tool than linux diff command
  • Setup for homebrew install
  • Test Suite
