How to use this image ?

This docker image has to be deployed to Docker Engine on one of supported Cloud providers or your own system. The instructions for creating Docker Engine vary by Cloud provider. We recommend to use [Docker Machine (beta)] (https://docs.docker.com/machine/) to provision Docker Engine.

In order to use the image, it is necessary to accept the terms of the DB2 Express-C license. This is achieved by specifying the environment variable LICENSE equal to accept when running the image.

This docker image contained pre-deployed DB2 Express-C with the default DB2 instance, db2inst1.

1 - Start a container

docker run -it -p 50000:50000 -e DB2INST1_PASSWORD=db2inst1-pwd -e LICENSE=accept ibmcom/db2express-c:latest bash

• -p 50000:50000 exposes port 50000 to allow connections from the remote client.
• By specifying -e DB2INST1_PASSWORD=db2inst1-pwd parameter, you set a password of your choice for the db2inst1 user for the default DB2 instance.
• By specifying -e LICENSE=accept parameter, you are accepting this License to use the software contained in this image.

2 - Start DB2 and create sample DB Please switch to the default db2 instance user db2inst1 to start DB2 instance and create a sample database if you want :

$ su - db2inst1
$ db2start
$ db2sampl

• The time of creating a sample database depends on your system performance, which may take several minutes.
• You can create another database using db2 create db <dbname> command.

3 - Note

1. Start as a daemon You can start a container as a daemon with DB2 services up/running :

docker run -d -p 50000:50000 -e DB2INST1_PASSWORD=db2inst1-pwd -e LICENSE=accept ibmcom/db2express-c:latest db2start

• db2start, db2 services start automatically and remote client can connect to it at port 50000

2) Mount a volume While starting a Docker container, you can mount a volume from a directory on the Docker host like the following command :

docker run -it -p 50000:50000 -e DB2INST1_PASSWORD=db2inst1-pwd -e LICENSE=accept -v $(pwd):/share ibmcom/db2express-c:latest bash

• /share, referring to mount point at "/share" in the Docker.
• $(pwd), the current directory on Docker host while running Docker command, which is mounted by Docker container. It can also be any existing directory on Docker host, like /tmp, /opt, etc.
• If you want to use the mounted volume for DB2 system or data storage, please update DB2 manager configuration according to IBM Knowledge Center

3) DB2 is deployed in the Docker Engine in:

/opt/ibm/db2/V10.5
