thorsager/dev_glassfish repository overview

⁠Glassfish

This Dockerfile creates an image that will run Glassfish. It is to be used as the basis for thin Web-application images.

• https://hub.docker.com/r/thorsager/glassfish/⁠

The is a twist though. To control the behaviour of the applications Environment variables will be added to Glassfish System.properties.

All environment variables defined in the container at execution of entrypoint, with a name starting with GF_ENV_, will be transferred to the Glassfish System.properties, without the GF_ENV_ prefix.

  $ export GF_ENV_NAME=Pablo

Would be available as:

  System.getProperty("NAME");

The System.properties can also be referenced in resources defined in domain.xml added by asadmin

⁠Admin

The admin-password for remote admin of the GlassFish is glassfish this cannot be change at runtime a new image must be build for this to be altered.

⁠Debugging

If the DEBUG environment variable is set (non-zero length) debug will be enabled and debugger will be exposed on port 9009.
