Answer 1

Just try a different docker version. If you have a fixed version like:

deployment:
  services:
    - docker:19.03.13-dind

Changing it to latest might be enough:

deployment:
  services:
    - docker:latest-dind

But if you had latest like:

deployment:
  services:
    - docker:latest-dind

means that the latest version is buggy, so moving to a previous version might work (this version worked for me!):

deployment:
  services:
    - docker:20.10.22-dind

Finally, mind that if your image is based on docker, like:

deployment:
  image: docker:19.03.13
  services:
    - docker:19.03.13-dind

you'd need to adjust it too
