GitHub Action
Automate Updatecli with GitHub Action
Description
Updatecli is better when executed regularly so let see how to use this GitHub Action install Updatecli in your GitHub runner so you can use it.
Migration
From V1 to v2
The updatecli action v1 was a "GitHub Action" of type docker. While It was easier to start with, that type of GitHub Action runs in a docker container and so in a fully isolated environment. In many situations, updatecli leverages other tools. So switching to a Javascript GitHub action, allows to install Updatecli directly on the GitHub Action runner next to those other tools. Now, the goal of this GitHub action evolved from running updatecli to installing updatecli.
Parameter
Version
version: specifies the Updatecli version to install. Accepted values are any valid releases such as v0.25.0.
The default value corresponds to the latest Updatecli version
Required: false
Example
The current example takes its inspiration from the repository jenkins-infra/jenkins-infra.
Once you have your update strategy configuration in the directory ./updatecli/updatecli.d, you need following files in order to run updatecli from Github Action.
./updatecli/values.yaml
