100 -# The supported environment variables that can be overridden are:
101 -# - DB_USER: the name of the user configured for XWiki in the DB. Default is "xwiki". This is used to configure
102 -# xwiki's hibernate.cfg.xml file.
103 -# - DB_PASSWORD: the password for the user configured for XWiki in the DB. Default is "xwiki". This is used to
104 -# configure xwiki's hibernate.cfg.xml file.
105 -# - DB_DATABASE: the name of the database to use. Default is "xwiki". This is used to configure xwiki's
106 -# hibernate.cfg.xml file.
107 -# - DB_HOST: The name of the host (or docker container) containing the database. Default is "db". This is used to
108 -# configure xwiki's hibernate.cfg.xml file.
109 -# - CONTEXT_PATH: The name of the context path under which XWiki will be deployed in Tomcat. If not specified then it'll
110 -# be deployed as ROOT.
111 -# - JDBC_PARAMS: Replaces the default JDBC parameters with the passed ones.

116 -# Starts XWiki by starting Tomcat. All options passed to "docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]"
117 -# are also passed to docker-entrypoint.sh. If "xwiki" is passed then XWiki will be configured the first time the
118 -# container executes and Tomcat will be started. If some other parameter is passed then it'll be executed to comply
119 -# with best practices defined at https://github.com/docker-library/official-images#consistency.
