CLI error reference

Overview and description of common errors in the Score reference implementation CLI’s (score-compose, score-helm)

2 minute read

When debugging errors, use the --help flag or turn on diagnostic message with the --verbose flag on the CLI.

Workload does not have any containers

If you receive the following error, you may not have specified a container in your score.yaml file.

building docker compose configuration: workload does not have any containers to convert into a compose service

To resolve this error, declare a container.

containers:
  container-id:
    image: busybox

Container incorrectly specified

If you receive the following error, you may not have specified a string name for the container rather than a map of strings.

validating workload spec: 1 error(s) decoding:

* 'containers[image]' expected a map, got 'string'

For example, you may have your containers declared like the following.

# snippet does not work.
# do not copy
containers:
  image: busybox

To resolve this error, declare a container.

containers:
  container-id:
    image: busybox

container-id is an example name and can be updated with anything you want.

Duplicated key

If you receive an error similar to the following, you may have a duplicated key in your score.yaml file.

Error: yaml: unmarshal errors:
  line 28: mapping key "required" already defined at line 27

To resolve, remove the duplicated key.

Resource variable names not resolving

If your score.yaml file contains variables that don’t resolve, you may have indented incorrectly.

# snippet does not work
# do not copy
apiVersion: score.dev/v1b1

metadata:
  name: hello-world

containers:
  hello:
    image: busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo Hello $${FRIEND}!; sleep 5; done"]
  variables:
    FRIEND: ${resources.env.NAME}

resources:
  env:
    type: environment

In the previous code snippet, the variables parameter is adjusted too far left. It should be aligned with the image, command, and args parameters.

apiVersion: score.dev/v1b1

metadata:
  name: hello-world

containers:
  hello:
    image: busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo Hello $${FRIEND}!; sleep 5; done"]
    variables:
      FRIEND: ${resources.env.NAME}

resources:
  env:
    type: environment

Alternatively, you could have the map of the variables set incorrectly.

# snippet does not work
# do not copy
apiVersion: score.dev/v1b1

metadata:
  name: hello-world

containers:
  hello:
    image: busybox
    command: ["/bin/sh"]
    args: ["-c", "while true; do echo Hello $${FRIEND}!; sleep 5; done"]
    variables:
      FRIEND: ${resources.friend.NAME}

resources:
  env:
    type: environment

The FRIEND parameter is set to resources.friend.NAME, but that is not a valid path in the resources section.
