Deploy at Gitlab CI with docker-compose fails - docker

Question

I deployed my app from the local machine before by:
> docker context create remote --docker "host=ssh://user#myhost"
> docker --context remote ps
> docker-compose --context remote build
> docker-compose --context remote up -d
This is successful, all Dockerfiles are right.
Now I want to do the same but at GitLab CI. This is my gitlab-ci.yml file for building:
image: docker:19.03.12
services:
- docker:dind
stages:
- build
install_dependencies:
stage: build
before_script:
- 'command -v ssh-agent >/dev/null || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- echo "StrictHostKeyChecking no " > ~/.ssh/config
script:
- echo "Building deploy package"
- echo "$NPMRC" > ~/.npmrc
- apk add --no-cache docker-compose
- docker context create remote --docker "host=ssh://user#myhost"
- docker --context remote ps
- docker context use remote
- docker-compose --context remote build
- echo "Build successful"
Everything goes right before docker-compose --context remote build, when --context arg is not recognized, I can't understand why.
$ docker context use remote
Current context is now "remote"
Warning: DOCKER_HOST environment variable overrides the active context. To use "remote", either set the global --context flag, or unset DOCKER_HOST environment variable.
remote
$ docker-compose --context remote build

Answer 1

To fix this, docker-compose version should be at least 1.26.0.
