Own docker image.

[er2de2]

I would like to create my own docker image. Which files do I need to edit to make it point to my repository?

Hey,

I'm assuming you're only interested in building the image for a single platform and architecture, in which case it should be just about editing the Dockerfile to:

FROM alpine:3.19

WORKDIR /app
COPY build/glance /app/glance

EXPOSE 8080/tcp
ENTRYPOINT ["/app/glance"]

You can build Glance with:

go build -o build/glance .

And then build the image with:

docker build -t er2de2/glance:latest .

The tag, specified with the -t option is what determines the name of your image. You can then push that image to your repository with:

docker push er2de2/glance:latest

Thank you for the clarification

I create my own docker image , but when i try to deploy on my server terminal show me:
exec /app/glance: no such file or directory

What do you get if you list the contents of the directory with this command?

docker run --rm --entrypoint /bin/ls er2de2/glance -la /app

[er2de2]

docker run --rm --entrypoint /bin/ls romandrajer/glance:2.0 -la /app
total 16068

Ah, right - I forgot about CGO, my bad! Try building Glance with this command and then repeat building the image and then pushing with the previous commands:

CGO_ENABLED=0 go build -o build/glance .

Now everything work perfect. Thank you very much.
