DaCHS on Docker

This part will use the classical procedure define in the DaCHS implementation to fill the two configuration files (gavo.rc and defaultmeta.txt) EPN-TAP Server Installation for VESPA Data Provider Tutorial. Also replace the logos respecting the size for big and medium. Using Docker container instead of virtual box is more easy and quicker to install and may allow your IT service to publish your data without managing an Debian server.

1. First install Docker on your machine :
   As Docker is a container system in constant evolution, get the current version in the official site adapted to your operating system and follow the installation procedure . https://docs.docker.com/install/
2. We will use the Docker image done by Carlos Brandt available on Docker hub, then we will use another Docker for the statistc of usage (Awstat). 
3. To be able to have persistent storage of the config files, the data and the logs we will use Docker volume storage on your hard disk. This proposed volume come with a very simple exemple of Vespa service containing physical constant of the solar system planet's. all these files are inside the docker_kit.zip docker_kit.zip. Unzip it in the my_path directory.
   
   
4. edit the gavo.rc file in the directory gavoetc (replace with you personal info)

   corsOriginPat: http.*                                                                                                                  (to allow cross plateform for javascript)
   logFormat: combined                                                                                                                (to allow ip address in logs for awstats)

   authority: vopdc.obspm                                                                                    (this is your naming authority ID used in the registry)
   
   
5. edit the defaultmeta.txt file in the directory gavoetc (replace with you personal info)

6. To launch the Docker and export the volume use command line, If you have an application running on your laptop using port 80 (like apache), you may close it. replace my_path by the path where the files are

1. sudo docker run -it -p 80:80 --volume my_path/mydisk/planets:/var/gavo/inputs/planets --volume my_path/logs/:/var/gavo/logs/ --name mydachs chbrandt/dachs:latest

2. Then, from outside Dachs (i.e.: do it from another terminal window) you have to copy files from your local storage to the Docker container 

   sudo docker cp my_path/gavoetc/gavo.rc mydachs:/etc/gavo.rc sudo docker cp my_path/gavoetc/defaultmeta.txt mydachs:/var/gavo/etc/defaultmeta.txt sudo docker exec -it mydachs mkdir -p /var/gavo/web/nv_static/img sudo docker cp my_path/img/logo_big.png mydachs:/var/gavo/web/nv_static/img/logo_big.png sudo docker cp my_path/img/logo_medium.png  mydachs:/var/gavo/web/nv_static/img/logo_medium.png

3. To launch Postgres and install the service planets as a first example and launch DaCHS

   sudo docker exec -it mydachs /etc/init.d/postgresql restart sudo docker exec -it --user dachsroot mydachs  gavo imp planets/q sudo docker exec -it --user dachsroot mydachs  gavo pub //services sudo docker exec -it --user dachsroot mydachs  gavo pub //tap sudo docker exec -it --user dachsroot mydachs  gavo pub planets/q sudo docker exec -it mydachs gavo serve restart

   Then simply type 127.0.0.1 in your browser to access your Dachs server.
   

   To reopen a session after login out: sudo docker exec -it mydachs bash
   
   

4. Now make a container with AWSTATS from a debian container.  Make sure you have adapted the two config files of awstats and apache ( my_path/conf/awstats.dachs.conf and my_path/conf/25-myserver.mydomain.conf

   sudo docker run -it --name myawstats -p 8080:80 -v my_path/logs/:/var/gavo/logs/ debian sudo docker exec -it myawstats apt-get -y update sudo docker exec -it myawstats apt-get -y upgrade sudo docker exec -it myawstats apt-get -y install awstats sudo docker exec -it myawstats apt-get -y install apache2 sudo docker exec -it myawstats apt-get -y install geoip-database sudo docker exec -it myawstats apt-get -y install libgeo-ipfree-perl sudo docker cp mypath/conf/awstats.dachs.conf myawstats:/etc/awstats/awstats.dachs.conf sudo docker cp mypath/conf/25-myserver.mydomain.conf \ myawstats:/etc/apache2/sites-enabled/25-myserver.mydomain.conf

5. Make the stats run on the container

To see if it works try to open a browser with first 127.0.0.1 to see DaCHS main page, and after  http://127.0.0.1:8080/cgi-bin/awstats.pl?output=alldomains&config=dachs&framename=index
