singularity-keycloak

Singularity recipe repository for Keycloak authentication server.

Building the container requires sudo privileges. To make the container executable for non-root users perform the following:

To build, you must make the container writable:

::

$ singularity build --writable keycloak.img Singularity

You must also assign write permissions to all users:

::

$ chmod a+rwx keycloak.img

To run the container as a non-root user successfully:

First declare the following environment variables and export them. Their defaults are given in this listing:

::

SINGULARITYENV_PORT="8080"
SINGULARITYENV_IPADDR="127.0.0.1"
SINGULARITYENV_CONFIGFILE="/home/coop/betus/singHackFull/keycloak/keycloakConfig.json"
SINGULARITYENV_REALM_NAME="CanDIG"
SINGULARITYENV_ADMIN_USERNAME="admin"
SINGULARITYENV_ADMIN_PASSWORD="admin"
SINGULARITYENV_USER_USERNAME="user"
SINGULARITYENV_USER_PASSWORD="user"
export SINGULARITYENV_PORT
export SINGULARITYENV_IPADDR
export SINGULARITYENV_CONFIGFILE
export SINGULARITYENV_REALM_NAME
export SINGULARITYENV_ADMIN_USERNAME
export SINGULARITYENV_ADMIN_PASSWORD
export SINGULARITYENV_USER_USERNAME
export SINGULARITYENV_USER_PASSWORD

Then run the singularity image as writable:

::

$ singularity run --writable keycloak.img

When uploading the built image as a release, compress the image using gzip first:

::

gzip keycloak.img
