Gogs: PR-5322

Add new Dockerfile.docker-ce for docker-ce(>=v17.06) to build Gogs’s docker image

Docker-CE can be given to a new build stage by adding AS name to the FROM instruction sine release version of v17.06. The Dockerfile’s FROM instruction like below:

FROM

FROM <image> [AS <name>]

Or

FROM <image>[:<tag>] [AS <name>]

Or

FROM <image>[@<digest>] [AS <name>]

• Optionally a name can be given to a new build stage by adding AS name to the FROM instruction. The name can be used in subsequent FROM and COPY --from=<name|index> instructions to refer to the image built in this stage.

Find Docker-ce official document here.

You can use this patch to build docker image if docker-ce that version >=v17.06 is installed:
