Provisioned by it economics GmbH
Docker images provided within this repository are built on the needs of it economics GmbH.
The LimeSurvey Image is based on our base Apache with current PHP version 7.2.
Minimal usage is to provide at least mandatory environmental variables from next chapter – so base usage can look like this [given that there is a Docker container databasecontainer within the Docker network internal and the given user credentials]:
docker run \
--rm -d -P \
--network internal \
-e DB_HOST=databasecontainer \
-e DB_NAME=database \
-e DB_USER=user \
-e DB_PASS=password \
-e LIMESURVEY_ADMIN=admin \
-e LIMESURVEY_ADMIN_PASS='$uper-secur3' \
-e LIMESURVEY_ADMIN_NAME=Admin \
-e LIMESURVEY_ADMIN_MAIL='admin@example.net' \
-e LIMESURVEY_SHOW_SCRIPT_NAME=true \
