    find ${HOME}/.docker/ -name 'config.json'
find /etc/docker/ -name 'daemon.json'
find /etc/systemd/system/docker.service.d/ -name 'http-proxy.conf'
  2. If the configuration files are found and their absolute paths are returned, run the following commands to collect these configuration files.
    1. Create a temporary directory for storing the configuration files.
      1
      mkdir -p ${HOME}/DockerConf
    2. Package the found configuration files in sequence.

      tar -Pczvf ${HOME}/DockerConf/config.json.tar.gz ${HOME}/.docker/config.json
tar -Pczvf ${HOME}/DockerConf/daemon.json.tar.gz /etc/docker/daemon.json
tar -Pczvf ${HOME}/DockerConf/http-proxy.conf.tar.gz /etc/systemd/system/docker.service.d/http-proxy.conf
    3. Package the directory where the preceding packages are stored. Use DockerConf.tar.gz as an example:
      cd /root && tar -czvf DockerConf.tar.gz DockerConf
  3. Obtain the source components using either of the following methods:
    • If you select the Upload source component package option, return to the Add Component Information tab, and click Upload next to Upload source component package to upload the source component package.
    • If you select the Obtain from node server option, run the following command to decompress the source component package.
      1. Log in to the tool through SSH and upload the package to the user-defined directory on Target Node.
      2. Set the package path to Source Component Path, for example, /home/DockerConf.tar.gz.
  4. After the packaging is complete, delete the ${HOME}/DockerConf directory.
