docker - 通过 packer 构建 docker 容器并通过 chef-solo 进行配置在启动服务时失败
问题描述
以下是构建 centos:7 docker 镜像的更大镜像工厂模板的摘录。一切都按预期工作，但是我在正在运行的容器上收到 dbus 错误。任何帮助表示赞赏！
相同的代码在以下情况下有效：
- 我使用
vmware-iso或virtualbox建设者。 - 我用一张
centos:6图片
我尝试过的没有效果：
- 切换到
chef-client -z - 添加
/sys/fs/cgroup:/sys/fs/cgroup:ro音量 - 添加
privileged到 docker builder
模板：
{
"builders": [{
"type": "docker",
"image": "centos:7",
"privileged": true,
"changes": [
"ONBUILD RUN {{ isotime }}"
],
"volumes": {
"/sys/fs/cgroup": "/sys/fs/cgroup:ro"
},
"export_path": "~/tmp/party_parrot.tar"
}],
"provisioners": [{

"chef"
],
"prevent_sudo": true,
"run_list": [
"redhat_factory::default"
],
"chef_license": "accept",
"type": "chef-solo"
}]
}
厨师食谱：
package 'tuned'
service 'tuned' do
action %i(start enable)
end

连接到正在运行的容器：
[root@a74a6b2cfa39 /]# systemctl --system status tuned
Failed to get D-Bus connection: Operation not permitted
[root@a74a6b2cfa39 /]# systemctl --system start tuned
Failed to get D-Bus connection: Operation not permitted
提前致谢！
解决方案
我已经能够通过以下方式修改我的工作来解决这个问题：
- 修改
run_command具体的entrypoint属性 - 添加
tmpfs数组 - 最后修改chef provisioner的暂存目录
打包机模板：
