retry

Retries an Action step on failure or timeout. This is currently intended to replace the run step for moody commands.

NOTE: Ownership of this project was transferred to my personal account nick-fields from my work account nick-invision. Details here

Inputs

`timeout_minutes`

Required Minutes to wait before attempt times out. Must only specify either minutes or seconds

`timeout_seconds`

Required Seconds to wait before attempt times out. Must only specify either minutes or seconds

`max_attempts`

Required Number of attempts to make before failing the step

`command`

Required The command to run

`retry_wait_seconds`

Optional Number of seconds to wait before attempting the next retry. Defaults to 10

`shell`

Optional Shell to use to execute command. Defaults to powershell on Windows, bash otherwise. Supports bash, python, pwsh, sh, cmd, and powershell per docs

`polling_interval_seconds`

Optional Number of seconds to wait while polling for command result. Defaults to 1

`retry_on`

Optional Event to retry on. Currently supports [any (default), timeout, error].

`warning_on_retry`

Optional Whether to output a warning on retry, or just output to info. Defaults to true.

`on_retry_command`

Optional Command to run before a retry (such as a cleanup script). Any error thrown from retry command is caught and surfaced as a warning.

`new_command_on_retry`

Optional Command to run if the first attempt fails. This command will be called on all subsequent attempts.

`continue_on_error`

Optional Exit successfully even if an error occurs. Same as native continue-on-error behavior, but for use in composite actions. Defaults to false

`retry_on_exit_code`

Optional Specific exit code to retry on. This will only retry for the given error code and fail immediately other error codes.

Outputs

`total_attempts`

The final number of attempts made

`exit_code`

The final exit code returned by the command

`exit_error`

The final error returned by the command

Retry using continue_on_error input (in composite action) but allow failure and do something with output

- uses: nick-fields/retry@v2
  id: retry
  with:
    timeout_seconds: 15
    max_attempts: 3
    continue_on_error: true
    command: node -e 'process.exit(99);'
- name: Assert that step succeeded (despite failing command)
  uses: nick-fields/assert-action@v1
  with:
    expected: success
    actual: ${{ steps.retry.outcome }}
- name: Assert that action exited with expected exit code
  uses: nick-fields/assert-action@v1
  with:
    expected: 99
    actual: ${{ steps.retry.outputs.exit_code }}

Retry using continue-on-error built-in command (in workflow action) but allow failure and do something with output

- uses: nick-fields/retry@v2
  id: retry
  # see https://docs.github.com/en/free-pro-team@latest/actions/reference/workflow-syntax-for-github-actions#jobsjob_idcontinue-on-error
  continue-on-error: true
  with:
    timeout_seconds: 15
    max_attempts: 3
    retry_on: error
    command: node -e 'process.exit(99);'
- name: Assert that action failed
  uses: nick-fields/assert-action@v1
  with:
    expected: failure
    actual: ${{ steps.retry.outcome }}
- name: Assert that action exited with expected exit code
  uses: nick-fields/assert-action@v1
  with:
    expected: 99
    actual: ${{ steps.retry.outputs.exit_code }}
- name: Assert that action made expected number of attempts
  uses: nick-fields/assert-action@v1
  with:
    expected: 3
    actual: ${{ steps.retry.outputs.total_attempts }}

Run script after failure but before retry

uses: nick-fields/retry@v2
with:
  timeout_seconds: 15
  max_attempts: 3
  command: npm run some-flaky-script-that-outputs-something
  on_retry_command: npm run cleanup-flaky-script-output

Run different command after first failure

uses: nick-fields/retry@v2
with:
  timeout_seconds: 15
  max_attempts: 3
  command: npx jest
  new_command_on_retry: npx jest --onlyFailures

Run multi-line, multi-command script

name: Multi-line multi-command Test
uses: ./
with:
  timeout_minutes: 1
  max_attempts: 2
  command: |
    Get-ComputerInfo
    Get-Date

Run multi-line, single-command script

name: Multi-line single-command Test
uses: ./
with:
  timeout_minutes: 1
  max_attempts: 2
  shell: cmd
  command: >-
    echo "this is
 a test"

Requirements

NodeJS is required for this action to run. This runs without issue on all GitHub hosted runners but if you are running into issues with this on self hosted runners ensure NodeJS is installed.

Ownership

As of 2022/02/15 ownership of this project has been transferred to my personal account nick-fields from my work account nick-invision due to me leaving InVision. I am the author and have been the primary maintainer since day one and will continue to maintain this as needed.

Existing workflow references to nick-invision/retry@<whatever> no longer work and must be updated to nick-fields/retry@<whatever>.
