Managing containers

To manage your containers, you can define them in the custom.containers field in your serverless.yml configuration file.

Each container must specify the relative path to its directory, which contains the Dockerfile, and all files related to the application:

custom:
  containers:
    mycontainer:
      directory: my-container-directory
      buildArgs:
        MY_BUILD_ARG: "my-value"
      env:
        MY_VARIABLE: "my-value"

Below is an example of a project structure corresponding to the example above, crucially the my-container-directory contains all the files necessary for the container build.

.
├── my-container-directory
│   ├── Dockerfile
│   ├── requirements.txt
│   ├── server.py
│   └── (...)
├── node_modules
│   ├── serverless-scaleway-functions
│   └── (...)
├── package-lock.json
├── package.json
└── serverless.yml

Serverless Containers automatically have a PORT environment variable set, which indicates which port the container's webserver should be listening on. By default PORT is 8080. You can change this via the port variable in your container definition.

See the container example for more information.
