github-action-push-to-another-repository

When to use this GitHub Action? It is useful in case that you have a GitHub repository with a a directory that you want to push to another GitHub repository using GitHub Actions (automated on push, for example). It is also useful if using GitHub Actions you generate certain files that you want to push to another GitHub repository.

Flow:

The example repository has a MarkDown file main.md), during the GitHub Actions flow it executes build.sh and the output/ directory (configurable via source-directory appears in the output repository.

Please bear in mind: files in the target repository are deleted. This is to make sure that it contains only the generated files in the last run without previously generated files.

There are different variables to setup the behaviour:

Inputs

source-directory (argument)

From the repository that this Git Action is executed the directory that contains the files to be pushed into the repository.

destination-github-username (argument)

For the repository https://github.com/cpina/push-to-another-repository-output is cpina.

destination-repository-name (argument)

For the repository https://github.com/cpina/push-to-another-repository-output is push-to-another-repository-output

Warning: this Github Action currently deletes all the files and directories in the destination repository. The idea is to copy from an output directory into the destination-repository-name having a copy without any previous files there.

user-email (argument)

The email that will be used for the commit in the destination-repository-name.

user-name (argument) [optional]

The name that will be used for the commit in the destination-repository-name. If not specified, the destination-github-username will be used instead.

destination-repository-username (argument) [optional]

The Username/Organization for the destination repository, if different from destination-github-username. For the repository https://github.com/cpina/push-to-another-repository-output is cpina.

target-branch (argument) [optional]

The branch name for the destination repository. It defaults to main for historical reasons, feel free to change it to main.

commit-message (argument) [optional]

The commit message to be used in the output repository. Optional and defaults to "Update from $REPOSITORY_URL@commit".

The string ORIGIN_COMMIT is replaced by $REPOSITORY_URL@commit.

API_TOKEN_GITHUB (environment)
