19.3. 使用 runlabels 运行 support-tools

流程

1. 拉取 support-tools 镜像：

   # podman pull registry.redhat.io/rhel10/support-tools

   Copy to Clipboard

2. 为 support-tools 显示 install runlabel：

   # podman container runlabel install --display rhel10/support-tools
   command: podman run --rm --privileged -v /:/host -e HOST=/host -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools registry.redhat.io/rhel10/support-tools:latest /bin/install.sh

   Copy to Clipboard

   此时该命令会为主机打开权限，将主机 root 文件系统挂载到容器中的 /host，并运行 install.sh 脚本。

3. 对 support-tools 运行 install runlabel：

   # podman container runlabel install rhel10/support-tools
   command: podman run --rm --privileged -v /:/host -e HOST=/host -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools registry.redhat.io/rhel10/support-tools:latest /bin/install.sh
   Creating directory at /host//etc/pki/support-tools
   Creating directory at /host//etc/support-tools.d
   Installing file at /host//etc/support-tools.conf
   Installing file at /host//etc/sysconfig/support-tools
   Installing file at /host//etc/logrotate.d/syslog

   Copy to Clipboard

   这会在 host -tools 镜像以后要使用的主机系统上创建文件。

4. 为 support-tools 显示 run runlabel：

   # podman container runlabel run --display rhel10/support-tools
   command: podman run -d --privileged --name support-tools --net=host --pid=host -v /etc/pki/support-tools:/etc/pki/support-tools -v /etc/support-tools.conf:/etc/support-tools.conf -v /etc/sysconfig/support-tools:/etc/sysconfig/support-tools -v /etc/support-tools.d:/etc/support-tools.d -v /var/log:/var/log -v /var/lib/support-tools:/var/lib/support-tools -v /run:/run -v /etc/machine-id:/etc/machine-id -v /etc/localtime:/etc/localtime -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools --restart=always registry.redhat.io/rhel10/support-tools:latest /bin/support-tools.sh

   Copy to Clipboard

   这表明，在启动 support-tools 容器来运行 support-tools d 守护进程时，命令会打开主机中的特定文件和目录，并在容器内挂载特定的文件和目录。

5. 为 support-tools 执行 run runlabel：

   # podman container runlabel run rhel10/support-tools
   command: podman run -d --privileged --name support-tools --net=host --pid=host -v /etc/pki/support-tools:/etc/pki/support-tools -v /etc/support-tools.conf:/etc/support-tools.conf -v /etc/sysconfig/support-tools:/etc/sysconfig/support-tools -v /etc/support-tools.d:/etc/support-tools.d -v /var/log:/var/log -v /var/lib/support-tools:/var/lib/support-tools -v /run:/run -v /etc/machine-id:/etc/machine-id -v /etc/localtime:/etc/localtime -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools --restart=always registry.redhat.io/rhel10/support-tools:latest /bin/support-tools.sh

   Copy to Clipboard

   support-tools 容器会打开特权，挂载主机需要的内容，并在后台运行 support-toolsd 守护进程(-d)。support-toolsd 守护进程开始收集日志消息，并将信息定向到 /var/log 目录中的文件。

6. 为 support-tools 显示 uninstall runlabel：

   # podman container runlabel uninstall --display rhel10/support-tools
   command: podman run --rm --privileged -v /:/host -e HOST=/host -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools registry.redhat.io/rhel10/support-tools:latest /bin/uninstall.sh

   Copy to Clipboard

7. 为 support-tools 运行 uninstall runlabel:

   # podman container runlabel uninstall rhel10/support-tools
   command: podman run --rm --privileged -v /:/host -e HOST=/host -e IMAGE=registry.redhat.io/rhel10/support-tools:latest -e NAME=support-tools registry.redhat.io/rhel10/support-tools:latest /bin/uninstall.sh
