README

This repository contains a list of common Updatecli published on ghcr.io/updatecli/policies/**

HOWTO

Login

Even though all Updatecli policies published on ghcr.io are meant to be public, you’ll probably need to authenticate to reduce rate limiting by running:

docker login ghcr.io

Publish

Each policies defines in this repository are automatically published on ghcr.io via a GitHub Action workflow

Show

We can see the content of the policy by running:

updatecli manifest show ghcr.io/updatecli/policies/<a policy name>:latest

Use

They are two ways to execute an Updatecli policy, either running one policy or several policies at once.

One policy can be executed by running:

updatecli apply --config ghcr.io/updatecli/policies/<a policy name>:latest

Important

Any values files specified at runtime will override default values setting from the policy bundle

Assuming we have a file named update-compose.yaml, multiple policies can be composed and executed by running:

updatecli compose apply

update-compose.yaml

policies:
    - policy: "ghcr.io/updatecli/policies/autodiscovery/golang:latest"
    - policy: "ghcr.io/updatecli/policies/autodiscovery/npm:latest"

More information about Updatecli compose feature can be found here

CONTRIBUTING

Policies can be added by creating a new folder under updatecli/policies directory. The subfolder path will be used as the policy name.

For example if we want to create a policy named autodiscovery/golang, we need to create a folder named updatecli/policies/autodiscovery/golang. This policy will be named ghcr.io/updatecli/policies/autodiscovery/golang and will be published on ghcr.io docker registry.

The policy folder must contain:

• Policy.yaml file which contains the policy metadata.

• updatecli.d directory which contains the policy configuration files.

• README.md file which contains the policy documentation.

• CHANGELOG.md file which contains the policy changelog.

• values.yaml file which contains the default values for the policy.

Policy.yaml

The Policy.yaml file must contain at least the following fields:

url: <link to this git repository>
documentation: <link to the policy documentation>
source: <link to this policy code>
version: <policy version>
description: <policy description with maximum 512 characters>

Version

The version must be a valid semantic version. For example 1.0.0 or 1.0.0-beta.1 The version will be used as the "tag" for the policy such as ghcr.io/updatecli/policies/autodiscovery/golang:1.0.0

Any change to the policy code must be reflected by a new version. Policies are automatically published on ghcr.io if the version is updated.

FAQ

Why a monorepo ?

A monorepo is a repository that contains multiple projects. In our case, we have a single repository that contains multiple Updatecli policies.

We are still in a very early stage and we are not sure yet if we will keep this repository as a monorepo or if we will split it into multiple repositories.

But it is easier to handle a monorepo than multiple repositories while we build the tooling and the process to manage Updatecli policies.
