adduser not found on amazoncorretto:11

[jmcnulty-mosaic]

Expected behaviour

Latest version of sbt-native-packager resolves this issue: #1262
However I am still seeing this with the latest version of sbt-native-packager 1.7.6 when I sbt docker:publishLocal
This happened after I updated my base image to amazoncorretto:11. This was the only change in the project.

Actual behaviour

sbt docker:publish fails

Information

, my project/plugins.sbt:
addSbtPlugin("com.typesafe.sbt" % "sbt-native-packager" % "1.7.6")

The native packager settings that I added to my project:
dockerBaseImage := "amazoncorretto:11"

My build error:

Thanks @jmcnulty-mosaic for the detailed issue 🤗

If you don't need a special user you can deactivate this by adding

Docker / daemonUserUid := None,
Docker / daemonGroupGid := None

If you do require this feature then what's the equivalent call in the amazon corretto docker image?

Thanks muuki88 for the quick response. Looks like my build does need that user so I'll need to figure out the answer to your question. I'm finding contradictory info so far so I've got a ways to go. Amazon Corretto should be Debian and Debian allegedly has adduser. I say "should be" since I haven't connected all the dots yet from the corretto:11 Dockerfile to a debian distribution and the fact that adduser clearly isn't present raises some doubt. I'll update this ticket with what I find once I have verified the details myself.

amazoncorretto:11 is based on the Amazon Linux 2 image, which doesn't seem to have adduser by default: amazonlinux/container-images#28

I can work around this with:

    dockerBaseImage := "amazoncorretto:11",
    dockerCommands := {
      val commands = dockerCommands.value
      val index = commands.indexWhere {
        case Cmd("RUN", args @ _*) => args.contains("demiourgos728")
        case _ => false
      }
      commands.patch(index, Seq(ExecCmd("RUN", "yum", "-y", "install", "shadow-utils")), 0)
    },

This will install the required dependencies before the adduser command is used:

[info] * Cmd(FROM,WrappedArray(amazoncorretto:11, as, stage0))
[info] * Cmd(LABEL,WrappedArray(snp-multi-stage="intermediate"))
[info] * Cmd(LABEL,WrappedArray(snp-multi-stage-id="a06a43ee-1963-4956-83f0-39dc0e6145d4"))
[info] * Cmd(WORKDIR,WrappedArray(/opt/docker))
[info] * Cmd(COPY,WrappedArray(opt /opt))
[info] * Cmd(USER,WrappedArray(root))
[info] * ExecCmd(RUN,List(chmod, -R, u=rX,g=rX, /opt/docker))
[info] * ExecCmd(RUN,List(chmod, u+x,g+x, /opt/docker/bin/application))
[info] * DockerStageBreak
[info] * Cmd(FROM,WrappedArray(amazoncorretto:11))
[info] * Cmd(USER,WrappedArray(root))
[info] * ExecCmd(RUN,WrappedArray(yum, -y, install, shadow-utils))
[info] * Cmd(RUN,List(id, -u, demiourgos728, 1>/dev/null, 2>&1, ||, ((, getent, group, 0, 1>/dev/null, 2>&1, ||, (, type, groupadd, 1>/dev/null, 2>&1, &&, groupadd, -g, 0, root, ||, addgroup, -g, 0, -S, root, )), &&, (, type, useradd, 1>/dev/null, 2>&1, &&, useradd, --system, --create-home, --uid, 1001, --gid, 0, demiourgos728, ||, adduser, -S, -u, 1001, -G, root, demiourgos728, ))))
[info] * Cmd(WORKDIR,WrappedArray(/opt/docker))
[info] * Cmd(COPY,WrappedArray(--from=stage0 --chown=demiourgos728:root /opt/docker /opt/docker))
[info] * Cmd(EXPOSE,WrappedArray(9000))
[info] * Cmd(USER,WrappedArray(1001:0))
[info] * ExecCmd(ENTRYPOINT,List(/opt/docker/bin/application))
[info] * ExecCmd(CMD,List())

But it does feel a bit messy.

Another workaround is to use amazoncorretto:11-alpine, which includes adduser already.

EDIT: although alpine does not include bash, which is causing other problems.

Another workaround:

    daemonUserUid in Docker := None,
    daemonUser in Docker := "daemon"

Thanks for sharing everything you tried and worked.

Regarding the alpine / bash issue. There's an AshScriptPlugin that overrides the bash scripts and should work with alpine.
