Required Environment Variables

There are a number of installation parameters available for use in configuring unattended installation of InterSystems IRIS instances on UNIX and Linux; their use is described and they are listed in Unattended InterSystems IRIS Installation. If you install InterSystems IRIS instance from a kit in your Dockerfile, rather than using an InterSystems image as a base as described in Creating InterSystems IRIS Images, the installation parameters that are required as environment variables in the container runtime environment must also be built into the image; without them, container creation from the image will fail. These variables are included in all images from InterSystems and are shown, with the values set by InterSystems, in the following table:

Installation Parameters Required as Environment Variables for Containerization

Parameter/Variable	Description	InterSystems Value
ISC_PACKAGE_INSTANCENAME	Name of the instance to be installed.	IRIS
ISC_PACKAGE_INSTALLDIR	Directory in which the instance will be installed.	/usr/irissys
ISC_PACKAGE_IRISUSER	Effective user for the InterSystems IRIS superserver.	irisowner
ISC_PACKAGE_IRISGROUP	Effective user for InterSystems IRIS processes.	irisowner
ISC_PACKAGE_MGRUSER	Username of the installation owner.	irisowner
ISC_PACKAGE_MGRGROUP	Group that has permission to start and stop the instance.	irisowner

Note:

If you are building your own InterSystems IRIS image, you can optionally set the IRISSYS variable to specify the registry directory. InterSystems sets it to /home/irisowner/irissys in all images. If you do not include this environment variable, the registry directory is /usr/local/etc/irissys.

The environment variables discussed here are used to specify the configuration details described in Ownership and Directories.
