Using the preconfigured IBM Db2 Docker image

Rather than install the IBM Db2 Database and manually configure it for use with HCL Commerce, you can simply launch the preconfigured IBM Db2 Docker image as your development or test database.

Important: This IBM Db2 Docker container must be used for test purposes only. Under no circumstance can this Docker image be used as your staging or production database.

Before you begin

Download the latest HCL Commerce Version 9 Docker images. Included in these images is the IBM Db2 Docker image.
Extract your IBM Db2 Docker image to a desired directory.
If you are using Centos 7, with the default store driver overlay, you must change the default storage driver to devicemapper. The IBM Db2 Docker image does not support the overlay storage driver. For more information about confuting the store driver in Docker, see Configure Docker with the devicemapper storage driver.

Procedure

Load the preconfigured IBM Db2 Docker image into Docker.
```
docker load -i Dockerimage
```
Where:

Dockerimage

The preconfigured IBM Db2 Docker image file name.
Run the preconfigured IBM Db2 Docker image.
```
docker run -d -e LICENSE=accept --privileged -p port:50000 --name name db2-docker-image
```
Where:

port

The port number that should be used for the host container, which is mapped to the internal database, running on port 50000.
For example, use 50001 if you want to connect to the containerized database on port 50001.

name

A label to identify the usage for the container.
For example, auth_db, to identify that the container is used for the authoring environment database.
Verify that your IBM Db2 instance is running in one of two ways:
- Use your IBM Db2 client to connect to the IBM Db2 service.
- Log in to the IBM Db2 container to connect to the IBM Db2 instance by running the following commands:
```
* docker exec -it db2ContainerId /bin/bash
* su - db2inst1
* db2 connect to mall user wcs using wcs1
```
  Where db2ContainerId is the IBM Db2 container ID.

What to do next
