# RUN EXAMPLES #
################

# ZoneMinder uses /dev/shm for shared memory and many users will need to increase 
# the size significantly at runtime like so:
#
# docker run -d -t -p 1080:443 \
#    --shm-size="512m" \
#    --name zoneminder \
#    zoneminder/zoneminder

# ZoneMinder checks the TZ environment variable at runtime to determine the timezone.
# If this variable is not set, then ZoneMinder will default to UTC.
# Alternaitvely, the timezone can be set manually like so:
#
# docker run -d -t -p 1080:443 \
#    -e TZ='America/Los_Angeles' \
#    --name zoneminder \
#    zoneminder/zoneminder

# ZoneMinder can write its data to folders outside the container using volumes.
#
# docker run -d -t -p 1080:443 \
#    -v /disk/zoneminder/events:/var/lib/zoneminder/events \
#    -v /disk/zoneminder/mysql:/var/lib/mysql \
#    -v /disk/zoneminder/logs:/var/log/zoneminder \
#    --name zoneminder \
#    zoneminder/zoneminder

# ZoneMinder can use an external database by setting the appropriate environment variables.
#
# docker run -d -t -p 1080:443 \
#    -e ZM_DB_USER='zmuser' \
#    -e ZM_DB_PASS='zmpassword' \
#    -e ZM_DB_NAME='zoneminder_database' \
#    -e ZM_DB_HOST='my_central_db_server' \
#    -v /disk/zoneminder/events:/var/lib/zoneminder/events \
#    -v /disk/zoneminder/logs:/var/log/zoneminder \
#    --name zoneminder \
#    zoneminder/zoneminder

# Here is an example using the options described above with the internal database:
#
# docker run -d -t -p 1080:443 \
#    -e TZ='America/Los_Angeles' \
#    -v /disk/zoneminder/events:/var/lib/zoneminder/events \
#    -v /disk/zoneminder/mysql:/var/lib/mysql \
#    -v /disk/zoneminder/logs:/var/log/zoneminder \
#    --shm-size="512m" \
#    --name zoneminder \
#    zoneminder/zoneminder

# Here is an example using the options described above with an external database:
#
# docker run -d -t -p 1080:443 \
#    -e TZ='America/Los_Angeles' \
#    -e ZM_DB_USER='zmuser' \
#    -e ZM_DB_PASS='zmpassword' \
#    -e ZM_DB_NAME='zoneminder_database' \
#    -e ZM_DB_HOST='my_central_db_server' \
#    -v /disk/zoneminder/events:/var/lib/zoneminder/events \
#    -v /disk/zoneminder/logs:/var/log/zoneminder \
#    --shm-size="512m" \
#    --name zoneminder \
#    zoneminder/zoneminder
