This project builds on the openSUSE Java image here and includes Python version 2. It can be used as a base image by projects which require Python2.
Tini is pre-installed in the container. If the image entrypoint is not overwritten then it will be automatically used.
PostgreSQL Client is pre-installed in the container. psql is a terminal-based front-end to PostgreSQL. It enables you to type in queries interactively, issue them to PostgreSQL, and see the query results. Alternatively, input can be from a file or from command line arguments. In addition, psql provides a number of meta-commands and various shell-like features to facilitate writing scripts and automating a wide variety of tasks.
Any executable scripts added to the /startup/startup.d/ directory will be automatically run each time the container is started (assuming the image entrypoint is not overwritten).
The image comes pre-installed with a startup script which provides a mechanism to extend the CA certificates which should be trusted.
The image comes pre-installed with a utility script which can be used to check if a PostgreSQL database exists and to create it if it does not.
When the script is called it must be passed an environment variable prefix for the service:
/scripts/check-create-pgdb.sh SERVICE_
The script then reads the database details from a set of environment variables with the specified prefix:
| Environment Variable | Description |
|---|---|
SERVICE_DATABASE_HOST |
The host name of the machine on which the PostgreSQL server is running. |
SERVICE_DATABASE_PORT |
The TCP port on which the PostgreSQL server is listening for connections. |
SERVICE_DATABASE_USERNAME |
The username to use when establishing the connection to the PostgreSQL server. |
SERVICE_DATABASE_PASSWORD |
The password to use when establishing the connection to the PostgreSQL server. |
SERVICE_DATABASE_APPNAME |
The application name that PostgreSQL should associate with the connection for logging and monitoring. |
SERVICE_DATABASE_NAME |
The name of the PostgreSQL database to be created. |
