⁠HSQLDB Docker Image

https://github.com/infotechsoft/docker-hsqldb⁠

BASE IMAGE: openjdk:11-jre-slim
HSQLDB v2.7.0

Usage:

docker run -v ${pwd}/test:/docker-entrypoint-initdb.d -p 9001:9001 --name hsqldb infotechsoft/hsqldb:2.7.0

Add scripts into /docker-entrypoint-initdb.d

# Startup Options
HSQLDB_TRACE=false # print Java stack traces
HSQLDB_SILENT=true # do not print SQL statements
HSQLDB_REMOTE=true # allow remote access
HSQLDB_PORT=9001   # listen on port
HSQLDB_DATABASE_NAME=hsqldb # auto-create/connect to database
HSQLDB_DATABASE_ALIAS=test # database alias
HSQLDB_USER=sa     # database username
HSQLDB_PASSWORD=   # database password

On startup, docker-entrypoint.sh generates HSQLDB server.properties and SQLTOOL sqltool.rc configuration files.

If there are no files in DATABASE volume matching HSQLDB_DATABASE_NAME,

1. Check to see if there are any .sql scripts in docker-entrypoint-initdb.d and execute them with sqltool.
2. Start hsqldb using the startup options

HSQL_HOME::
/opt/hsqldb/

DATABASE Volume:
/opt/database/

⁠SQLTOOL

sqltool is installed in /opt/hsqldb. It is used to run startup scripts, and can be used to connect and query the HSQLDB database within the Docker container.
The sqltool.rc file is generated to run the initial SQL scripts using a FILE connection. Note: hsqldb creates a file lock on the database. You will need to override the sqltool configuration to connect to the local server.

Usage:

java -jar /opt/hsqldb/sqltool.jar --rcFile=/opt/hsqldb/sqltool.rc init

⁠Shutdown

To gracefully shutdown HSQLDB, send a SHUTDOWN sql command to the database. This will perist temporary data, but it will not terminate the HSQLDB Java process. Subsequent connections will fail.

There may be a problem with using CTRL+C to terminate the container. Use docker stop instead.
