Description

for easier distribution of the cdm-server it would be advantageous to package the cdm-server into a docker container.

Docker doc:

Running java inside docker containers:

On creating docker containers with maven:

The fabric8io/docker-maven-plugin seems to the the most mature and suitable plugin.

On configuring containers and images via ENV and ARGS, etc: https://vsupalov.com/docker-arg-env-variable-guide

On running a container as a system service, restart policies etc.

==> we should use

docker run -dit --restart unless-stopped  
  • -d, --detach : Run container in background and print container ID
  • -i, --interactive: Keep STDIN open even if not attached
  • -t, --tty: Allocate a pseudo-TTY

  • --restart unless-stopped: Restart the container unless it is explicitly stopped or Docker itself is stopped or restarted.

Deployment

to https://hub.docker.com

Organization for the EDIT Platform:

https://cloud.docker.com/u/cybertaxonomy/

  • organization name: cybertaxonomy
  • owners:
    • kohlbecker
  • repository: cdm-server
  • team : editdev
    • members (so far):
      • kohlbecker
      • jenkinsintbgbm (jenkins-int-AT-bgbm.org)

The cdm-server image is available from https://hub.docker.com/r/cybertaxonomy/cdm-server/

To push images with maven add the following server section to the ~/.m2/settings.xml

    <server>
        <id>docker.io</id>
        <username>username</username>
        <password>S3cr3t</password>
    </server>

Wir versuchen hier am Museum Teile unserer Infrastruktur mit Docker zu realisieren.

Mit jsvc hab ich ein paar Probleme das im Docker zum laufen zu bekommen.

Spricht etwas dagegen die jar „normal“ zu starten mit

java $JAVA_OPTIONS -jar cdm-server.jar $CDMSERVER_ARGS

jsvc macht unter Docker ziemliche Probleme, an dieser Stelle sind wir auch schon stecken geblieben als wir mal auf die Schnelle den cdm-server in Docker verpacken wollten.
Die jar normal zu starten ist natürlich möglich, allerdings läuft der Server dann nicht als Hintergrundprozess, für Produktionssysteme nicht gerade optimal.

Jetty hatte früher auch jsvc verwendet um als Daemon zu starten, mittlerweile wird das bei Jetty aber auch anders gemacht. Ich habe mir das alles noch nicht im Detail angesehen aber ein Ticket dafür angelegt: #5375

Ich habe auch großes Interesse daran eine solide Lösung für dieses Problem zu finden.

Viele Grüße
Andreas

Ob der CDM im Docker-Container als Daemon läuft oder nicht sollte ja egal sein. Man kann den Docker-Prozess ja als Hintergrund-Prozess starten.
Ich hab gelesen, dass jsvc auch dafür benutzt wird um den Prozess neu zu starten, wenn er abstürzt. Dass kann ja Docker prinzipiell auch, obwohl ich damit noch keine Erfahrungen gemacht habe. (restart=always)

Falls es dich interessiert hab ich mal das Dockerfile angehängt, mit dem ich das Image baue. Im Ordner .cdmLibrary liegt nur die datasource.xml und cdm-server-realm.properties:

FROM anapsix/alpine-java:8

COPY cdm-server-4.0.0.jar /root/cdm-server.jar
COPY cdmserver/.cdmLibrary /root/.cdmLibrary

#-Dspring.profiles.active=remoting is needed for the Taxonomic Editor to connect to the cdm server
ENV NAME=cdmserver \
    DESC="CDM Server" \
    CDM_HOME=/root \
    LOGDIR="/log/$NAME" \
    CONTEXT_PATH_PREFIX=/ \
    CDMSERVER_PORT=8080 \
    CDMSERVER_SHUTDOWN=30
ENV JAVA_OPTIONS="-Xmx1024M -XX:PermSize=128m -XX:MaxPermSize=192m -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled -Duser.home=$CDM_HOME -Dspring.profiles.active=remoting"

ENV CDMSERVER_ARGS="-httpPort=$CDMSERVER_PORT -logdir=$LOGDIR -contextPathPrefix=$CONTEXT_PATH_PREFIX"

EXPOSE $CDMSERVER_PORT

CMD java $JAVA_OPTIONS -jar /root/cdm-server.jar $CDMSERVER_ARGS

Viele Grüße
