Error: Failed to create a container of

Overview

You have a freestyle step that is failing with the following error message:

[SYSTEM]                                                                 
  Message             Failed to run freestyle step: my_step
  Caused by           Failed to create a container of:
                      ...

Details

You’re duplicating a mount point (${{CF_VOLUME_PATH}} = /codefresh/volume). For example:

my_step:
  image: my_image
  commands:
    - ls /codefresh/volume
    ...
  volumes:
    - '${{CF_VOLUME_NAME}}:${{CF_VOLUME_PATH}}' # this will make this step fail

The pipeline volume is automatically mounted in a freestyle step. And it’s available at /codefresh/volume in the container used for the freestyle step.

Trying to mount something in that path would cause an error. This is the specific error that is happening behind the scenes:

Error: (HTTP code 400) unexpected - Duplicate mount point: /codefresh/volume

Remove the duplicated mount point definition.

Following the example presented in the Cause section, the step definition should look like this:

my_step:
  image: my_image
  commands:
    - ls /codefresh/volume
    ...

If you need to mount a specific directory of your pipeline volume, you will need to mount it to another path. For example:

my_step:
  image: my_image
  commands:
    - ls /codefresh/volume
    ...
  volumes:
    - './relative-dir/under-cf-volume:/absolute-path/for-the-dir'

Note: the ... represent other commands to be executed, or other fields for the freestyle step. They should not be part of the freestyle step definition
