⁠About Micro Integrator profile of WSO2 Enterprise Integrator

The Micro Integrator profile of WSO2 Enterprise Integrator is architectured to be container-friendly so that it allows you to perform advanced scenarios without sacrificing the speed required for a container-based architecture. Because its start-up time is faster than the ESB profile, microservices are designed to start up very quickly, perform a specific task, and then shut down. You can also use the Micro Integrator profile to orchestrate atomic microservices into composite microservices that address more complex, real-world scenarios.

⁠How to use this image.

⁠Start a Micro Integrator profile instance

The following command starts a Linux Ubuntu-based Micro Integrator profile Docker image.

$ docker run -it -p 8290:8290 -p 8253:8253 --name micro-integrator wso2/wso2ei-micro-integrator:6.4.0

Here, ports 8290 and 8253 have been mapped to the corresponding Docker host (host machine on top of which containers are spawned) ports.

⁠Container shell access and viewing server logs

Assuming you have started a Docker container instance of Micro Integrator profile as instructed in the previous section Start a Micro Integrator profile instance,

• The Micro Integrator server log is available through Docker's container log:

$ docker logs micro-integrator

• The Docker exec command allows you to run commands inside a Docker container. The following command line will give you a bash shell inside the container you created:

$ docker exec -it micro-integrator bash

⁠Pass arguments during server startup

⁠Running in debug mode

To start a Docker container instance of the Micro Integrator profile in debug mode (assuming 5005 to be the remote debugging port), use the following command:

$ docker run -it -p 8290:8290 -p 8253:8253 -p 5005:5005 --name another-micro-integrator wso2/wso2ei-micro-integrator:6.4.0 -debug 5005

Note: Passing arguments during server startup is not supported in Docker image with tag 6.3.0.

⁠How to update configurations

Configurations would lie on the Docker host machine and they can be volume mounted to the container. As an example, the steps required to change the port offset using carbon.xml is as follows:

• Stop the Micro Integrator profile container if it's already running.

In the Micro Integrator profile product distribution, carbon.xml configuration file can be found at {DISTRIBUTION_HOME}/wso2/micro-integrator/conf. Copy the file to a suitable location of the host machine, referred to as {SOURCE_CONFIGS}/carbon.xml and increase the offset value under ports by 1.

• Grant read permission to other users for {SOURCE_CONFIGS}/carbon.xml.

$ chmod o+r {SOURCE_CONFIGS}/carbon.xml

• Run the image by mounting the file to the container as follows:

$ docker run -p 8291:8291 -p 8254:8254 --volume {SOURCE_CONFIGS}/carbon.xml:{TARGET_CONFIGS}/carbon.xml wso2/wso2ei-micro-integrator:6.4.0

Here, {TARGET_CONFIGS} refers to /home/wso2carbon/wso2ei-6.4.0/wso2/micro-integrator/conf folder of the container.
