saiku

These files building a container-image of saiku and starting it up.

Features

• Env-Variable $SAIKU_HOME is set to
• mountable data-location for persistent data
  • Environment-Variable is called INSTANCEDIR
  • per default this is /saiku/data
• automatic license-upload on bootstrap
  • mount the license-File to /saiku_license.lic
  • updating a license is done through http://container-url/upload.html
• bootstrapping additional cube-configurations (files has to be mounted in /additionalCubes)
• executing bootstrap-shellscripts (files has to be mounted in /additionalCubes)

Usage

1. generate an license and provide it to the docker-container

2. use the file docker-compose.yml (Alternatively you could pull the image from docker-hub docker pull gaerfield/saiku)

   version: '2'
   services:
     saiku:
       build:
         context: https://github.com/gaerfield/saiku.git
       image: saiku
       ports:
         - 8080
       volumes:
         # mounts used only for bootstraping (containers first creation)
         - ./config/saiku_license.lic:/saiku_license.lic
         - ./config/cubes:/additionalCubes
         - ./config/bootstrapScripts:/docker-entrypoint-initdb.d
         # used for persistence (overwritten when bootstrapping!)
         - ./data/saiku:/saiku/data/

3. docker-compose up -d and you're done

FAQ (or stuff I asked myself)

Is it possible to use a different tomcat-image as base-image?

I don't know about a compatible way of doing that. The binary release of ships it's own version of tomcat, which is somewhat suspicious. Also custom startup-scripts are used. So for backwards-compatibility it's maybe best to use, what's shipped by saiku.

Howto configure additional Java-Arguments?

Normally on could to that through the setenv.sh-file or additional Java-Arguments. For Saiku this is not the case. Saiku ships with a custom startup-script, which sets the java-arguments hardcoded. For a backwards-compatible approach, I would:

• either: copy Saiku's startup-script and mount it into $SAIKU_HOME/start-saiku.sh (per default /saiku/start-saiku.sh)
• or: provide a shell-script within docker-entrypoint-initdb.d that does some sed-magic to replace the arguments within the startup-script (beware of the fact, that this script is only executed once)

Why the docker-entrypoint-initdb.d - folder?

sh-Files within the folder get's executed in alphabetical order during bootstrap (the first time, the container starts up) before Saiku is started. Use it for example to download an additional library that is needed for running saiku (i.e. the mysql-connector-library gets downloaded by the example-script in installMysqlLib.sh).
