ecs-upload-task

A very simple cli tool that will upload an ecs task and optionally update a service to reference it.

Designed as a partner tool to https://github.com/buildkite/ecs-run-task and shares the same task definition parser with environment substitution.

Example

Install it

go install github.com/99designs/ecs-upload-task@latest

or

curl -L --fail -o /usr/bin/ecs-upload-task \
  <release from https://github.com/99designs/ecs-upload-task/releases>

taskdefinition.yml

family: hello-world
containerDefinitions:
- essential: true
  image: ${IMAGE_NAME:-99designs/hello-world}
  memory: 64
  cpu: 10
  name: hello-world
  portMappings:
    - {containerPort: 1234, hostPort: 1234}
  environment:
    - {name: PORT, value: "1234"}

then take it for a dry-run to validate that the template is parsed successfully.

ecs-upload-task --file taskdefinition.yml --dry-run
Template taskdefinition.yml is parsed successfully

then register the task definition

ecs-upload-task --file taskdefinition.yml

Create a new ECS service referencing the task definition. Service templates can use the family name without the version, simply hello-world is enough.

Later, in your automated CI pipeline you can deploy by simply:

export IMAGE_NAME=99designs/hello-world:$FRESH_BUILD_NUMBER
ecs-upload-task --file taskdefinition.yml --service hello-world-2017-05-15-10-45

Creating a new release

  1. Check out the the commit you want to create a release for, and tag it with appropriate semver convention:
$ git tag vx.x.x
$ git push --tags
  1. Create the binaries:

Binaries are compiled using gox. This provides a simple way to compile for multiple CPU architectures (amd64, arm64), which allows us to provide support for devices such as M1 Macs.

gox can be installed via go install

go install github.com/mitchellh/gox@latest

Then simply run the Makefile to compile.

$ make

  1. Go to https://github.com/99designs/ecs-upload-task/releases/new

  2. Select the tag version you just created

  3. Attach the binaries from ./bin/*
