Create and Configure Docker Registry

About this task

Use this section to create and configure docker registry.

Procedure

  1. From the Plant Applications Enterprise Edition Web Client installation package, download the DTR2023 folder to the machine on which you want to run Docker Registry.
    Note:
    It is not mandatory to have local registry DTR2023. However, due to security concerns, we recommend to have a new local registry (DTR2023).
    Note:
    Ensure that you have enough space (minimum 50 GB) to store these extracted files.
  2. Create another folder named docker.service.d in the /etc/systemd/system folder by running the following command: 
    sudo mkdir -p /etc/systemd/system/docker.service.d
  3. In the docker.service.d folder that you have created, create a file named http\u0002proxy.conf by running the following command: 
    sudo nano /etc/systemd/system/docker.service.d/http-proxy.conf
  4. Copy the following lines of code into the http-proxy.conf file, replacing the text in the angular brackets with the appropriate values: 
    [Service]
Environment="HTTP_PROXY=<proxy URL>:port/"NO_PROXY=localhost,127.0.0.1,<docker registry IP address>,<docker registry hostname>"
  5. Save the file and close it.
    Note:
    To save and close the file, enter Ctrl+O and Ctrl+X, respectively.
  6. Create a file named daemon.json in the following folder: /etc/docker
  7. Add the following lines of code in the daemon.json file:
    {
"insecure-registries" : ["<IP address of the Docker Registry node>:5000","<host name of the Docker Registry node>:5000"]
}
  8. Run the following commands to restart the docker: 
    sudo systemctl restart docker
  9. Using terminal, change directory (cd) to the DTR2023 folder.
  10. In the DTR2023 folder, change the permission of the PA_DTR_Start_Lix.sh file to 775 by running the following command: sudo chmod 775 ./PA_DTR_Start_Lix.sh.
  11. Execute the PA_DTR_Start_Lix.sh Shell script with sudo privileges: sudo ./PA_DTR_Start_Lix.sh. The output of the command looks similar to the following:


  12. Add the following to the Registry-url bullet:

    http:// <dockerregistry IP>/<docker registry hostname> :5000/v2/

    You should see the following text returned by the web server:

    {}
