Inputs
Input Name | Input Code | Required | Description |
|---|---|---|---|
| Docker File | FDDKR_INP_DOCKER_FILE | No | The path to the Docker File to build. If empty uses default Dockerfile. |
| Docker File Arguments | FDDKR_INP_DOCKER_FILE_ARGS | No | The docker file arguments to use. These are the ARG instructions in the docker file. KeyValue pairs should be separated by "|" and the key and value should be separated by ",". Example: key1,value|key2,value|key3,value |
| Docker Repository | FDDKR_INP_REPOSITORY | No | The image name/repository to create the image in. This is the REPOSITORY column when running the command 'docker images'. |
| Image Tag | FDDKR_INP_IMAGE_TAG | No | The tag to apply to the image. Example: 'latest'. |
Outputs
Output Name | Required | Description |
|---|---|---|
FDDKR_OUT_IMAGE_ID | No | The image id that was created from the operation. The IMAGE_ID column when running the command 'docker images'. |
Artifacts
This operation consumes a Dockerfile from the artifacts repository. Can also be overridden through the docker file input.
Endpoint Selection
This operation delegates the selection to the workflow developer to determine.
Endpoint Execution
This operations delegates the execution to the workflow developer to decide.
Special Considerations
Build Args were not consumed
If using the 'Docker File Arguments' input and the docker file doesn't contain a matching ARG instruction, the operation will fail with the following error:
'com.github.dockerjava.api.exception.DockerClientException: Could not build image: One or more build-args were not consumed, failing build.'
To correct this, either remove the key/value mapping from the input or add an ARG instruction for the missing key in your docker file.
Docker Repository Required?
The 'Docker Repository' input is not required to build the image but in order to make use of other docker functionality, like pushing to a registry, you need to specify a repository. If you forgot to specify a repository on build you can tag the image from the command line at any point.
docker tag %ImageId% %RepoName%:%tagName%
