Overview of the Issue

I'm trying to build a Docker image starting from gitlab/gitlab-runner official image. I have two files that are uploaded to the container using "file" provisioner. As docs say, the best way to upload file in root dirs is to upload files in /tmp and move them using "shell" provisioner. This is what I'm trying to do but the shell provisioner doesn't work. The strange thing is that the files disappear from /tmp when shell provisioner is executed and I cannot find them in the entire container.

Reproduction Steps

provisioner "file" {
  source      = "./templates/config.toml"
  destination = "/tmp/config.toml"
}
provisioner "file" {
  source      = "./templates/fargate.toml"
  destination = "/tmp/fargate.toml"
}
provisioner "shell" {
  inline = ["mv /tmp/*.toml /etc/gitlab-runner/"]
}

Packer version

From v1.8.2

Simplified Packer Template

source "docker" "gitlab_runner_manager" {
  image  = "gitlab/gitlab-runner"
  commit = true
}
build {
  name    = "gitlab-runner-manager"
  sources = ["source.docker.gitlab_runner_manager"]
  # add provisioners here.
  provisioner "file" {
    source      = "./templates/config.toml"
    destination = "/tmp/config.toml"
  }
  provisioner "file" {
    source      = "./templates/fargate.toml"
    destination = "/tmp/fargate.toml"
  }
  provisioner "shell" {
    inline = ["mv /tmp/*.toml /etc/gitlab-runner/*.toml"]
  }
}

Operating system and Environment details

Docker container gitlab/gitlab-runner ubuntu based.

I discovered that the container image I'm using is mounting a volume, so packer cannot write in it.
