I think supporting the “build:” directive on docker-compose yaml since podman can do both build and run containers Very common use case for a large audience using docker-compose transitioning and migrating to podman to have the functionality of “docker-compose build” followed by the normal “docker-compose up” Here is an example of using “build:” in one my labs for distributing tracing using nodejs and java https://cloudnative101.dev/electives/dist-trace/activities/lab1 I think is ok if it’s not supported from kube yaml pod just from a compose, since a podspec should not have any build directives - Carlos Santana @csantanapr

Hi Scott,
I'm looking for the same functionality. If that's OK I'd like to answer your question.
If we could see the source/origin docker-compose YAML,
The Yaml might get messed up so you can also get it from here: https://gist.github.com/rudolfvesely/4ad6f762eafbe5417f80ff469b690c38
I intentionally made it complicated to show various options from "docker-compose".
- "build: ." will use Dockerfile (in case of Podman this should be Containerfile) to build image. In other words this will run "docker build ." - "args" will define / overwrite values in "ARG" in Dockerfile/Containerfile - "dockerfile: ./foo/bar/containerfile_for_db" is used when Dockerfile has different name. In other words this will run "docker build --file=foo/bar/containerfile_for_db"
$ cat ./something/api.env
NODE_ENV=test
$ cat .env
TAG=v1.5
$ cat docker-compose.yml
version: "3.9" services: webserver: # "Dockerfile" is located in the working directory and will be used to build image build: . # build arguments (used in Dockerfile) args: APP_HOME: app # environment variables environment: FLASK_ENV: development dbserver: # "Dockerfile" has different name dockerfile: ./foo/bar/containerfile_for_db # environment variables in a file env_file: - ./something/api.env redis: # variable defined in ".env" image: "webapp:${TAG}" volumes: - logvolume01:/var/log ports: - "5000:5000"
Please let me know if you have other questions.
Kind regards,
