In order to paper over transient DockerHub and container startup issues, retry
docker compose up
up to two times in case of an error.Motivation
We are experiencing transient failures in DockerHub and when starting certain third-party dependencies.
Tips for reviewer
Since we are not capturing stdout/stderr, it is not possible to have a list of more specific retriable errors. We can not capture stdout/stderr easily because the docker progress animations are also sent to stderr, so they will no longer be displayed without additional hacking.
