Docker image for h2database.

These are just some simple examples how to create and use a H2 database. For comprehensive documentation please read the docs on the H2 homepage.

To display all available options, just execute:

docker run --rm renfis/h2database

To just create a non-persistent database to play around, do the following:

docker run --rm `# Delete the container after is is stopped` \
       -p 127.0.0.1:8092:8092 `# Bind port 8092 only to localhost` \
       renfis/h2database \
       -web `# Let server accept tcp connections (default port: 8092)` \
       -webAllowOthers `# Allow connections from outside the docker container` \
       -ifNotExists `# Allow creation of new databases`

Open http:https://localhost:8092 to connect to the database.

When the container is stopped, all data is deleted.

Often you want to create a database which is not bound to the container lifecycle.

1. Create a folder on your host machine. The folder name is data in this example.
2. Start the container
   • with web interface enabled (-web -webAllowOthers)
   • with data folder mounted (-v $(pwd)/data:/data)
   • with base directory specified to be this folder (-baseDir /data)

docker run --rm \
       -p 127.0.0.1:8092:8092 \
       -v $(pwd)/data:/data \
       renfis/h2database \
       -web \
       -webAllowOthers \
       -baseDir /data \
       -ifNotExists

Open http:https://localhost:8092 to connect to the database.

When the container is stopped, the data is persisted in the data folder and can be reused.

If you don't want to create the database using the web interface, you can also allow tcp connections. See next example.

This example is similar to the above one, except that we

• enable tcp connection
• do not allow creation of new databases

docker run --rm \
       -p 127.0.0.1:9092:9092 \
       -v $(pwd)/data:/data \
       renfis/h2database \
       -tcp \
       -tcpAllowOthers \
       -baseDir /data

More information how to start and connect to the server can be found in the official documentation.
