Docker context not found on GitLab when building multiarch image

Question

I am trying to build a multiarch image on GitLab CI with buildx and when I tried to run docker inside my pod I receive this error:

Failed to initialize: unable to resolve docker endpoint: context "/builds/infrastructure/apps/deployer": context not found: open /root/.docker/contexts/meta/726f8c8b439712b59d12acacc425f6720c7c4fd123a6503aa6a022b79cd18827/meta.json: no such file or directory

gitlab-ci.yml

build:

    - apt-get upgrade -y
    - apt-get install ca-certificates curl gnupg lsb-release -y
    - mkdir -m 0755 -p /etc/apt/keyrings
    - curl -fsSL https://download.docker.com/linux/ubuntu/gpg | gpg --dearmor -o /etc/apt/keyrings/docker.gpg

      --file $DOCKER_CONTEXT/Dockerfile \
      --tag $ECR_REGISTRY:$CI_COMMIT_SHA \
      --push $DOCKER_CONTEXT

I tried autenticate on my ECR and receive a error similar:

aws ecr get-login-password --region region | docker login --username AWS --password-stdin id.dkr.ecr.region.amazonaws.com
