By Default the Docker image doesn't have RTDB_OPCUAServer2 included while writing this article (2024 Q2). So this document is intended to guide you through the steps involved in installing and configuring the docker with RTDB_OPCUAServer2.

it’s needed to build an image with RTDB_OPCUAServer2
(refer: https://docs.cpmplus.net/docs/installation-on-docker#adding-packages for adding additional package to default docker image)

Build and run the docker image with Custom package

Docker File

Create a Dockerfile with following entry

FROM cpmplus-repository.abb.com/cpmplushistory/qa/x64
		RUN apt-get update &&\
		apt-get install -y cpmplusopcuaserver2

Build Image

Build the Image with following command

📘

Note:- The below command needs to be executed from the location where Dockerfile is placed

Note that there is a dot at the end which needs to be included while running the command

Where cpmpluswithuaserver2 is the custom name of the image which is being build, users can choose the name of their choice and use it. In this document we use the name cpmpluswithuaserver2as the image name in following steps.

Run the Container

Run the docker from the new image built in the above step

docker run --shm-size=1T --name cpmplusuaserver2 -d -p 443:443 -p 5080:80 -p 48031:48031 -v /var/lib/uaserver2_rtdbdata:/var/lib/rtdbdata  -t cpmpluswithuaserver2

Note: port UAserver2 by default uses port 48031

Config Changes

Once the docker is started need to do following changes to the ini file RTDB_OPCUAServer2_ExampleVtrinSettings.ini under the path /usr/share/cpmplus/netcore/ so that the node is discoverable when browsed from any client

Replace the existing Url=wss://[NodeName]/History?noproxy=1 with a new value Url=/var/lib/rtdbdata. with following command from the docker host

docker exec -it cpmplusuaserver2 nano /usr/share/cpmplus/netcore/RTDB_OPCUAServer2_ExampleVtrinSettings.ini

Enable RTDB_OPCUAServer2 to run as Service

Run below 2 commands from the docker host machine in order to enable RTDB_OPCUAServer2 to as in service.

docker exec -it cpmplusuaserver2 CSCommon_Cmd -setini /var/lib/rtdbdata/RTDB.INI Services RTDB-OPCUAServer2 ON

docker exec -it cpmplusuaserver2 CSCommon_Cmd -setini /var/lib/rtdbdata/RTDB.INI RTDB-OPCUAServer2 CmdLine "/usr/share/dotnet/dotnet /usr/share/cpmplus/netcore/RTDB_OPCUAServer2.dll -c /usr/share/cpmplus/netcore/RTDB_OPCUAServer2_SecuredApplication.xml -c /usr/share/cpmplus/netcore/RTDB_OPCUAServer2_basesettings.ini -c /usr/share/cpmplus/netcore/RTDB_OPCUAServer2_ExampleVtrinSettings.ini"

Note: - Make sure to use proper docker container name in the commands

UA Server Certificate Path

With the default settings the certificate will be created in the following path inside the docker container
