Container

Containers are the main resource type for a compute.

Base Properties​

resources:
  - code: website
    type: container
    data:
      image: website:latest
      port: 8080
      desired: 2
      cpu: 256
      memory: 512

Using environment variables from GitHub Actions​

You can access environment variable outputs from previous steps to generate dynamic values such as image names.

resources:
  - code: website
    type: container
    data:
      image: ${Repositories_Default_RepositoryUri}:${Image_Tag}

Container Environment Variables​

You can set environment variables for your container.

resources:
  - code: website
	type: container
	data:
    image: ${Repositories_Default_RepositoryUri}:${Image_Tag}
	  port: 8080
	  desired: 2
	  cpu: 256
	  memory: 512
	  env:
		SERVICE: website
		DATA_TYPE: pg
		DATA_PG_SSLMODE: require

You can also use the this keyword to grab values from any current resource specified in the file.

Any use of this must be wrapped inside double curly braces {{ }} and is formatted in the following way:

  • {{this:resource-code:property}}

For example, the below noops.yaml has two resources, the website container and the db database. We can access the db resource to set the DATABASE_URL environment variable.

resources:
  - code: db
    type: database
    data:
      cluster: website-cluster

  - code: website
    type: container
    data:
      image: ${Repositories_Default_RepositoryUri}:${Image_Tag}
      port: 8080
      desired: 2
      cpu: 256
      memory: 512
      env_vars:
        SERVICE: website
        DATA_TYPE: pg
        DATA_PG_SSLMODE: require
        DATA_PG_HOST: "{{this:db:host}}"
        DATA_PG_PORT: "{{this:db:port}}"

Secrets​

Access secrets stored in Amazon Secrets Manager using the {{secret:secret-name}} format

Secrets can also use the this keyword to grab values another resource (such as a database username / password).

resources:
  - code: db
    type: database
    data:
      cluster: website-cluster

  - code: website
    type: container
    data:
      image: ${Repositories_Default_RepositoryUri}:${Image_Tag}
      port: 8080
      desired: 2
      cpu: 256
      memory: 512
      env_vars:
        SERVICE: website
        DATA_TYPE: pg
        DATA_PG_SSLMODE: require
        DATA_PG_HOST: "{{this:db:host}}"
        DATA_PG_PORT: "{{this:db:port}}"
      secrets:
        DATA_PG_USERNAME: "{{this:db:userpass:username}}"
        DATA_PG_PASSWORD: "{{this:db:userpass:password}}"
        SECURITY_SIGNKEY: "{{secret:signkey}}"

Edges​

Edges are used to connect your compute to the internet. If do not want your compute exposed publicly, exclude adding one to your container.

The edges field refers to edges created in No_Ops. If you haven't created an edge yet, see how to create an edge.

resources:
  - code: website
	type: container
	data:
	  image: ${Repositories_Default_RepositoryUri}:${Image_Tag}
	  port: 8080
	  desired: 2
	  cpu: 256
	  memory: 512
      edge:
        edges:
          - edge: www.getnoops.com
            environment: prod
        rules:
          - path: "*"
            priority: 1000
        health:
          path: /
          port: 8080
          timeout: 25
          interval: 30
          unhealthy_threshold: 5
          healthy_threshold: 5

Overrides​

You can override the default values of a container resource per environment by specifying the overrides field.

resources:
  - code: website
	type: container
	data:
	  image: ${Repositories_Default_RepositoryUri}:${Image_Tag}
	  port: 8080
	  desired: 2
	  cpu: 256
	  memory: 512
      env_vars:
        API_URL: https://test.myapi.com

    overrides:
      environments:
        - environment: prod
          data:
            env_vars:
              API_URL: https://myapi.com
