Octopilot

Octopilot is a CLI tool designed to help you automate your Gitops workflow, by automatically creating and merging GitHub Pull Requests to update specific content in Git repositories.

If you are doing Gitops with GitHub-hosted repositories, Octopilot is your swiss army knife to propagate changes in your infrastructure.

Octopilot was initially developed at Dailymotion, and is a core component of our Gitops workflow - you can read our blog post Introducing Octopilot: a CLI to automate the creation of GitHub pull requests in your gitops workflow.

Features

written in Go, and has 0 dependencies - not even git
native support for manipulating YAML or JSON files - which are commonly used in the Gitops world to describe resources
native support for manipulating files encrypted with sops - because who wants to store non-encrypted sensitive data in git?
supports regex-based updates to any kind of files - for these times when you need raw power
supports executing any command/tool - because you don't want to be limited by what we support
supports multiple strategies to create/update the PRs
supports automatic merge of the PRs - once the pre-configured CI checks are green
can update one or more GitHub repositories from a single execution - including dynamically defined repositories, using a GitHub search query
can execute one or more update rules in a single execution

Documentation

Example

Updating multiple repositories, and executing multiple update rules at once:

$ octopilot \
    --github-token "my-github-token" \
    --repo "my-org/some-repo" \
    --repo "my-org/another-repo(merge=true)" \
    --repo "discover-from(env=PROMOTE_TO_REPOSITORIES)" \
    --repo "discover-from(query=org:my-org topic:my-topic)" \
    --update "yaml(file=config.yaml,path='version')=file(path=VERSION)" \
    --update "yq(file=helmfile.yaml,expression='(.releases[] | select(.chart == \"repo/my-chart\") | .version ) = strenv(VERSION)')" \
    --update "sops(file=secrets.yaml,key=path.to.base64encodedCertificateKey)=$(kubectl -n cert-manager get secrets tls-myapp -o template='{{index .data \"tls.key\"}}')" \
    --pr-title "Updating some files" \
    ...
