A simple nodejs utility to update yaml files in github.

In our GitOps process, the docker tags in our infrastructure git repos need to be updated whenever there's a new container build. We created Ocommit as a way of automating this process.

This package exposes both an CLI interface, and a NodeJS connector.

GITHUB_ACCESS_TOKEN is the only required env var. This is the personal access token for a github user/bot

| name | type | desc | env | cli | | ------------ | -------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------- | ---------------------------- | | repo | string | The name of the github repository. | REPO=<name> | --repo <name> | | pr | boolean | Whether or not to open a PR. Will only do so if the target branch it different to the output branch. | CREATE_PR=true | --pr | | output | boolean | Whether or not to output the command response | | --o | | set | string[] | Key/value pairs to replace in the output file. Can either add a unique item to an array (will create if does not exist), add a property, or update a property. | | --set [path.to.var]=replacement --set [path.to.array[]]=new_value | | remove | string[] | key/value pairs of items to remove.

If the outputBranch already exists, it will use that/ If it does not, it will create a new branch | OUTPUT_BRANCH=branch-name | --outputBranch branch-name | | message | string | The desired github commit message | MESSAGE=chore(some-scope): some useful message | --message "chore(some-scope): some useful message" |

At the moment, this library only supports updating one file per commit.
