Field Detail

image

@Parameter(property="image",
           required=true)
private String image

Can be either an image ID (e.g. 8dbd9e392a96), or an image name with an optional tag. If no tag is specified, the docker daemon will automatically try to use the tag 'latest'.

skipDockerTag

@Parameter(property="skipDockerTag",
           defaultValue="false")
private boolean skipDockerTag

Flag to skip tagging, making goal a no-op. This can be useful when docker:tag is bound to the package goal, and you want to mvn package without tagging the image. Defaults to false.

newName

@Parameter(property="newName",
           required=true)
private String newName

The new name that will be applied to the source image. If a tag is not specified, the docker daemon will automatically apply the tag 'latest' to the specified repo. Only a repo without a tag should be specified if useGitCommitId is set to true.

pushImage

@Parameter(property="pushImage",
           defaultValue="false")
private boolean pushImage

Flag to push image after it is tagged.

tagInfoFile

@Parameter(property="tagInfoFile")
private String tagInfoFile

Path to JSON file to write when tagging images

useGitCommitId

@Parameter(property="useGitCommitId",
           defaultValue="false")
private boolean useGitCommitId

If specified as true, a tag will be generated consisting of the first 7 characters of the most recent git commit ID, resulting in something like image:df8e8e6. If there are any changes not yet committed, the string '.DIRTY' will be appended to the end. Note, if a tag is explicitly specified in the newName parameter, this flag will be ignored.
