Streamline your workflow and let this GitHub Action (a lite version of CLA Assistant) handle the legal side of contributions to a repository for you. CLA assistant GitHub action enables contributors to sign CLAs from within a pull request. With this GitHub Action we could get rid of the need for a centrally managed database by storing the contributor's signature data in a decentralized way - in the same repository's file system or in a remote repository which can be even a private repository.
- decentralized data storage
- fully integrated within github environment
- no User Interface is required
- contributors can sign the CLA or DCO by just posting a Pull Request comment
- signatures will be stored in a file inside the repository or in a remote repository
- signatures can also be stored inside a private repository
- versioning of signatures

CLA action workflow will be triggered on all Pull Request opened, synchronize, closed
. This workflow will always run in the base repository and that's why we are making use of the pull_request_target event.
When the CLA workflow is triggered on pull request closed
event, it will lock the Pull Request conversation after the Pull Request merge so that the contributors cannot modify or delete the signatures (Pull Request comment) later. This feature is optional.
CLA workflow creates a comment on Pull Request asking contributors who have not signed CLA to sign and also fails the pull request status check with a failure
. The contributors are requested to sign the CLA within the pull request by copy and pasting "I have read the CLA Document and I hereby sign the CLA" as a Pull Request comment like below.
If the contributor has already signed the CLA, then the PR status will pass with success
.
After the contributor signed a CLA, the contributor's signature with metadata will be stored in a JSON file inside the repository and you can specify the custom path to this file with path-to-signatures
input in the workflow.
The default path is path-to-signatures: 'signatures/version1/cla.json'
.
The signature can be also stored in a remote repository which can be done by enabling the optional inputs remote-organization-name
: <your org name>
and remote-repository-name
: <your repo name>
in your CLA workflow file.
NOTE: You do not need to create this file manually. Our workflow will create the signature file if it does not already exist. Manually creating this file will cause the workflow to fail.
If a GitHub username is included in the allowlist, they will not be required to sign a CLA. You can make use of this feature If you don't want your colleagues working in the same team/organisation to sign a CLA. And also, since there's no way for bot users (such as Dependabot or Greenkeeper) to sign a CLA, you may want to add them in allowlist
. You can do so by adding their names in a comma separated string to the allowlist
input in the CLA workflow file(in this case dependabot[bot],greenkeeper[bot]
). You can also use wildcard symbol in case you want to allow all bot users something like bot*
.
You have to create a Repository Secret with the name PERSONAL_ACCESS_TOKEN
.
This PAT should have repo scope and is only required if you have configured to store the signatures in a remote repository/organization.
