Usage

1. Store the version you need to validate in a file (eg. .version)
2. Trigger validate-version-action and pass all required inputs
3. Read out values from the outputs

Inputs

• version_filename (default: '.version') - Path to the file with application version
• github_token - Pass the secrets.GITHUB_TOKEN variable
• fail_on_error (default: 'false') - Fail the pipeline on version validation error

Outputs

• planned_version - Version from version file
• version_file_exists - False if version file doesn't exist
• tag_hash - Commit hash if version tag exists
• can_create - True if version tag can be created
• tag_exists - True if version tag already exists
• branch_name - Working branch name

Example

echo "1.0.0" > "${REPO_ROOT}/.version"
