Docker (Compose) has some quirks compared to Podman (Compose), e.g. when using gvisor or a lot of internal networks. Depending on what you do your milage will vary, though.
Agreed. I found compose overlay files merged list values differently between the Docker and Podman versions, which was a PITA in teams running Docker & Linux dev machines.
FWIW, most of these issues were recently fixed in podman-compose. I can now use the current git version of podman-compose interchangeably with docker-compose.
And one nice thing about podman-compose is that it's ONE PYTHON FILE. You can just copy it into your source tree.
