• --network The above example makes use of a container network - created, for example, using the command docker network create js7 - to allow network sharing between containers. Note that any inside ports used by containers are visible within a container network. Therefore an Agent running for the inside port 4445 is accessible in conjunction with the container's hostname and the same port within the container network.
• --publish The Agent is configured to listen to HTTP port 4445 by default. An outside port of the container's host can be mapped to the Agent's inside HTTP port. This is not required for use with a container network, see --network, however, it will allow direct access to the Agent from the container's host via its outside port .
• --env=RUN_JS_JAVA_OPTIONS This allows Java options to be injected into the Agent's container. Preferably this is used to specify memory requirements for the Agent, e.g. with -Xmx256m.
• --env=RUN_JS_USER_ID Inside the container the Agent is operated with the jobscheduler user account. In order to access files created by the Agent such as log files, and which are mounted to the container's host, it is recommended that you map the account that is starting the container to the jobscheduler account inside the container. The RUN_JS_USER_ID environment variable accepts the User ID and Group ID of the account that will be mapped. The above example makes use of the current user, for details see JS7 - Running Containers for User Accounts.
• --mount The following volume mounts are suggested:
  • var: This folder works as an entry point to the following sub-folders:
    • config: The configuration folder allows the specification of individual settings for the operation of the Agent - see the sections below and the JS7 - Agent Configuration Items article. Default settings are available on initial operation.
    • logs: In order to have persistent Agent log files they have to be written to a volume that is mounted for the container. Feel free to adjust the volume name from the src attribute. However, the value of the dst attribute should not be changed as it reflects the directory hierarchy inside the container.
    • state: The Agent requires a directory for journal information that should also be persistent. The journal is required to restore the state of orders when restarting the Agent.

  • Containers offers offer a number of methods for mounting volumes that include, for example, creating a local folder and mapping the folder to a volume before executing the docker run command listed above:

• sosberlin/js7:agent-2-5-0: The name of the base image is the same as that which was previously used with the docker pull command. Alternatively this could be sosberlin/js7:agent-2-5-0-plus for use of a "plus" image.
