Docker Container images for JS7 Agents provided by SOS make use of the following Dockerfile:

...

• Line 12 - 22: Default values are specified that are used if no command line arguments are provided. This includes values for:
  • the release number: adjust this value to the release of JS7 that you want to build an Agent for.
  • the repository which by default is sosberlin:js7.
  • the image name is determined from the current folder name and the release number.
  • the user id is by default the user id of the user running the build script.
  • the HTTP port and HTTPS port: if the respective port is not specified then the Agent will not listen to a port for the associated protocol. You can for example disable the HTTP protocol by specifying an empty value. The default ports should be fine as they are mapped by the run script to outside ports on the Docker container's host. However, you can modify ports as required.
  • Java options: typically you would specify default values e.g. for Java memory consumption. The Java options can be overwritten by the run script when starting the container. However, you might want to create your own image with adjusted default values.
• Line 27 - 50: The above options can be overwritten by command line arguments like this:

  
  

  Code Block
  language bash title Running the Build Script with Arguments linenumbers true
  ./build.sh --http-port=14445 --https-port=14443 --java-options="-Xmx1G"

• Line 54 - 63: The effective docker build command is executed with arguments. The Dockerfile is assumed to be located in the build sub-directory of the current directory.
