Hands-on exercises
==================

This text file lists the commands in the hands on excercise that I
showed during my presentation on "Experience with Docker and ICAT" at
the ICAT Meeting in Copenhagen in October 2016.

All docker images used can be found at Docker Hub, see
https://hub.docker.com/u/rkrahl/
Some commands however reference additional files from local disk with
configurations, not shown here.


0. Preparation

Start a set of three containers providing a complete working ICAT
installation.

docker volume create --name=gfdomain
docker volume create --name=storage
chown glassfish:glassfish /var/lib/docker/volumes/gfdomain/_data /var/lib/docker/volumes/storage/_data

docker run -d --name mysql -h mysql \
    -v /root/docker/common/init-icat.sql:/etc/mysql.d/init-icat.sql:ro \
    -v db:/var/lib/mysql \
    rkrahl/mariadb

docker run -d -p 4848:4848 -p 8181:8181 --name icat -h icat \
    --link mysql:mysql \
    -v /root/docker/common/icat-certs:/etc/glassfish/certs:ro \
    -v /root/docker/icat-4.8/icat:/opt/glassfish4/etc/icat:ro \
    -v gfdomain:/opt/glassfish4/glassfish/domains \
    -v storage:/srv/ids/storage \
    -e GF_DOMAIN_LIBS="/usr/share/java/mysql-connector-java.jar" \
    rkrahl/icat:4.8.0

docker run -d -p 443:443 --name apache -h apache \
    --link icat:icat \
    -v /root/docker/common/apache:/etc/apache2:ro \
    rkrahl/apache


1. On the host system as root

docker run -d --name mysql-test rkrahl/mariadb
docker exec -ti mysql-test bash
# ... show some content of the mysql-test container ...
docker kill mysql-test
docker rm mysql-test
cat /root/docker/common/init-icat.sql
docker run -d --name mysql-test -v /root/docker/common/init-icat.sql:/etc/mysql.d/init-icat.sql:ro rkrahl/mariadb
docker exec -ti mysql-test bash
# ... show some content of the mysql-test container ...
docker kill mysql-test
docker rm mysql-test

# Show the additional container already started during preparation:
docker ps -a
docker exec -ti icat bash


2. Inside the ICAT container

id
ls -la /etc/glassfish
ls -la /etc/glassfish/certs
ls -la /etc/glassfish.d
ls -la ~/apps
asadmin list-applications
ls -la ~/etc/icat
cat ~/etc/icat/APPS
cat /etc/glassfish.d/setup-icat.sh
