Description

Run an AWS ECS Fargate task and execute a custom commands. See the log output of the commands.

Details

This action makes it possible to run an AWS ECS Fargate task and execute custom commands. If the task definition is configured to log to CloudWatch, this action will try to tail the output of container, providing instant feedback inside the GitHub Workflow.

This action is great for executing migrations or other pre/post deployment steps for ECS Fargate applications.

Usage

Full example

- name: Execute migrations and seeders
  id: run-task
  uses: geekcell/[email protected]
  with:
    cluster: application-cluster
    task-definition: application-task-def
    assign-public-ip: 'DISABLED'

    subnet-ids: |
      subnet-04f133a104b9e95df
      subnet-0dc419ee6a1483514

    security-group-ids: |
      sg-123456789101112
      sg-112398765421333

    tail-logs: true
    override-container: app
    override-container-command: |
      /bin/sh
      -c
      php artisan migrate --force --ansi && php artisan db:seed --force --ansi
    override-container-environment: |
      AWS_REGION=us-east-1
      FOO=baz

    task-wait-until-stopped: true
    task-start-max-wait-time: 120
    task-stopped-max-wait-time: 300

Minimal example

- name: Run migration container
  id: run-task
  uses: geekcell/[email protected]
  with:
    cluster: application-cluster
    task-definition: application-task-def
    subnet-ids: subnet-04f133a104b9e95df
    security-group-ids: sg-123456789101112

Appending multiple lines into a single command

You can use the backslash character \ to append multiple lines into a single line. This is useful if you have many commands to execute and want to keep the YAML file readable. Otherwise, each line will be passed to the AWS ECS Fargate task as a separate argument.

Note: Make sure to use the | character so the YAML parser interprets the value as a multiline string. You can read more about this in the YAML documentation.

For example:

...
override-container-command: |
  /bin/sh
  -c
  php artisan down && \
  php artisan migrate --force --ansi && \
  php artisan db:seed --force --ansi && \
  php artisan cache:clear --ansi

Will pass the following command to the container on the AWS ECS Fargate task:

["sh", "-c", "php artisan down && php artisan migrate --force --ansi && php artisan db:seed --force --ansi && php artisan cache:clear --ansi"]

Inputs

parameter	description	required	default
task-definition	The name or the ARN of the task definition to use for the task.	true
subnet-ids	The list of subnet IDs for the task to use. If multiple they should be passed as multiline argument with one subnet ID per line.	true
security-group-ids	List of security group IDs for the task. If multiple they should be passed as multiline argument with one subnet ID per line.	true
assign-public-ip	Assign public a IP to the task. Options: ['ENABLED', 'DISABLED']	false	DISABLED
cluster	Which ECS cluster to start the task in.	false
override-container	Will use containerOverrides to run a custom command on the container. If provided, override-container-command must also be set.	false
override-container-command	The command to run on the container if override-container is passed.	false
override-container-environment	Add or override existing environment variables if override-container is passed. Provide one per line in key=value format.	false
tail-logs	If set to true, will try to extract the logConfiguration for the first container in the task definition. If override-container is passed, it will extract the logConfiguration from that container. Tailing logs is only possible if the provided container uses the awslogs logDriver.	false	true
task-wait-until-stopped	Whether to wait for the task to stop before finishing the action. If set to false, the action will finish immediately after the task reaches the RUNNING state (fire and forget).	false	true
task-start-max-wait-time	How long to wait for the task to start (i.e. reach the RUNNING state) in seconds. If the task does not start within this time, the pipeline will fail.	false	120
task-stopped-max-wait-time	How long to wait for the task to stop (i.e. reach the STOPPED state) in seconds. The task will not be canceled after this time, the pipeline will just be marked as failed.	false	300
task-check-state-delay	How long to wait between each AWS API call to check the current state of the task in seconds. This is useful to avoid running into AWS rate limits. However, setting this too high might cause the Action to miss the time-window your task is in the "RUNNING" state (if you task is very short lived) and can cause the action to fail.	false	6

Outputs

parameter	description
task-arn	The full ARN for the task that was ran.
task-id	The ID for the task that was ran.
log-output	The log output of the task that was ran, if tail-logs and task-wait-until-stopped are set to true.
