How to tag docker image with docker-compose
DockerDocker ComposeDocker Problem Overview
I want to build image via docker-compose and set specific tag to it. Documentation says:
> Compose will build and tag it with a generated name, and use that > image thereafter.
But I can't find a way to specify tag and for built images I always see 'latest' tag.

Solution 1 - Docker
It seems the docs/tool have been updated and you can now add the image tag to your script. This was successful for me.
Example:
version: '2'
services:
baggins.api.rest:
image: my.image.name:rc2
build:
context: ../..
dockerfile: app/Docker/Dockerfile.release
ports:
...
Solution 2 - Docker
Original answer Nov 20 '15:
No option for a specific tag as of Today. Docker compose just does its magic and assigns a tag like you are seeing. You can always have some script call docker tag <image> <tag> after you call docker-compose.
Now there's an option as described above or here
build: ./dir
image: webapp:tag
Solution 3 - Docker
I'd like to add that you can also manage your tag versions through environment variables or an .env file.
https://docs.docker.com/compose/environment-variables/#the-env-file
export TAG=1.11
Example:
version: '3.3'
services:
baggins.api.rest:
image: my.image.name:${TAG}
build:
context: ../..
dockerfile: app/Docker/Dockerfile.release
ports:
...
docker-compose config to validate
In my ci pipeline my first build is tagged with a throwaway value used for running tests. Then I change the tag to latest and rebuild again (nearly instant since it's all cached) before pushing to the registry.
Solution 4 - Docker
If you specify image as well as build, then Compose names the built image with the webapp and optional tag specified in image:
build: ./dir
image: webapp:tag
This results in an image named webapp and tagged tag, built from ./dir.
Solution 5 - Docker
you can try:
services:
nameis:
container_name: hi_my
build: .
image: hi_my_nameis:v1.0.0
Solution 6 - Docker
If you have already built your image, you can re-tag it by using the docker tag command:
docker tag imagename imagename:v1.0
docker tag imagename:v1.0 imagename:v1.1
If you have multiple tags attached to your repository, and if you want to remove one of them, you can use the docker rmi command:
$ docker rmi imagename:v1.0
Untagged imagename:v1.0

Solution 7 - Docker
Make sure your FROM statement in a Dockerfile contains the right image name.
