在Drone CI中testingAnsibleangular色，systemd服务不起作用

在testingAnsibleangular色时，我的systemd服务无法启动。 这是我得到的错误，

TASK [memcached : Packages Present] ******************************************** changed: [localhost] => (item=[u'memcached', u'libmemcached']) TASK [memcached : Service Enabled] ********************************************* fatal: [localhost]: FAILED! => {"changed": false, "msg": "Could not find the requested service memcached: host"} 

我的.drone.yml

 pipeline: build: image: samdoran/centos7-ansible privileged: true commands: - echo 'sslverify=0' >> /etc/yum.conf - yum install -y redhat-lsb-core python-devel openldap-devel git gcc gcc-c++ python2-pip - pip install -U pip tox - tox 

我的docker-compose.yml

 version: '2' services: drone-server: image: drone/drone:0.8 ports: - 8000:8000 - 9000 volumes: - /var/lib/drone:/var/lib/drone/ - /etc/ssl/certs/ca-bundle.crt:/etc/ssl/certs/ca-certificates.crt restart: always environment: - DRONE_OPEN=true - DRONE_HOST=https://example.server - DRONE_ADMIN=drone - DRONE_VOLUME=/etc/ssl/certs/ca-bundle.crt:/etc/ssl/certs/ca-certificates.crt - DRONE_GOGS_GIT_USERNAME=drone - DRONE_GOGS_GIT_PASSWORD=XXXXXXXX - DRONE_GOGS=true - DRONE_GOGS_URL=https://example.gogs - DRONE_SECRET=${DRONE_SECRET} drone-agent: image: drone/agent:0.8 command: agent restart: always depends_on: - drone-server volumes: - /var/run/docker.sock:/var/run/docker.sock environment: - DRONE_SERVER=drone-server:9000 - DRONE_SECRET=${DRONE_SECRET} - DOCKER_API_VERSION=1.24 

我已经尝试手动执行memcached安装，从我的fedora工作站启动一个基本的centos：7 docker容器，当–privileged服务启动时如预期的那样。 无人机泊坞窗运行在RHEL 7主机上。 我已经在Drone接口中将存储库设置为可信。

Answer 1

将/sys/fs/cgroup只读权限添加到volumes部分： - /sys/fs/cgroup:/sys/fs/cgroup:ro

这里的完整解释。

Answer 2

事实certificate，这个问题与入口命令是如何实现的有关，如果你覆盖了它不像预期那样启动的命令。 因此，解决方法是启动容器，分离，然后将命令发送到正在运行的容器。
