Question

我想为docker和ansible配置docker映像。我想使用高山作为基本图像。一些Docker映像（例如Alpine）不提供“ / bin / bash”。当打包程序运行该docker映像时，它将继续启动/ bin / bash。这将使构建过程崩溃：

dockerbuild.json：

{
  "builders": [
    {
      "type": "docker",
      "image": "alpine:3.8",
      "commit": true
    }
  ],
  "provisioners": [
    {
      "type": "ansible",
      "user": "root",
      "playbook_file": "playbook.yml",
      "extra_arguments": [
        "--extra-vars",
        "ansible_connection=docker"
      ]
    }
  ]
}

错误：

$> packer build dockerbuild.json
...
==> docker: Starting docker container...
    docker: Run command: docker run -v /Users/engi/.packer.d/tmp/packer-docker014300196:/packer-files -d -i -t alpine:3.8 /bin/bash
==> docker: Error running container: Docker exited with a non-zero exit status.
==> docker: Stderr: docker: Error response from daemon: OCI runtime create failed: container_linux.go:344: starting container process caused "exec: \"/bin/bash\": stat /bin/bash: no such file or directory": unknown.

我可以使用“ / bin / sh”或不使用显式shell来手动运行映像：

docker run --rm -i -t alpine:3.8 /bin/sh
docker run --rm -i -t alpine:3.8

您知道我如何打包程序告诉不启动/ bin / bash吗？

我在文档（惊奇）上找到了解决方案： run_command

https://www.packer.io/docs/builders/docker.html

这对我有用：

{
  "builders": [
    {
      "type": "docker",
      "image": "alpine:3.8",
      "commit": true,
      "run_command": ["-d", "-i", "-t", "{{.Image}}", "/bin/sh"]
    }
  ],
  "provisioners": [
    {
      "type": "ansible",
      "user": "root",
      "playbook_file": "playbook.yml",
      "extra_arguments": [
        "--extra-vars",
        "ansible_connection=docker"
      ]
    }
  ]
}
