Steps taken to get the Docker Web of Needs Swarm Running

**Actually, it does not seem to be a swam. it is running on one machine, but docker-compose is being used.

Beginning with https://github.com/researchstudio-sat/webofneeds/tree/master/webofneeds/won-docker I followed the steps:

(1) Install docker
Start with https://docs.docker.com/get-started/

(2) Install docker-compose
https://docs.docker.com/compose/overview/
and follow the tutorial
https://docs.docker.com/compose/gettingstarted/

(3) Create base_folder (mkdir data), .env file (see below), and docker-compose file (wget https://raw.githubusercontent.com/researchstudio-sat/webofneeds/master/webofneeds/won-docker/deploy/local/docker-compose.yml)

~/Documents/dockerexperiments/webofneeds$ ls -a
.  ..  data  docker-compose.yml  .env

~/Documents/dockerexperiments/webofneeds$ cat .env

deploy_host=localhost
base_folder=./data/



(4) Run docker compose in the same directory without the detached option to enable debugging:
sudo docker-compose up (also "sudo service tomcat7 stop" and "sudo service mongodb stop" to prevent port conflicts)

(5) There is an error when trying to create a resource over https on localhost. Here are some instructions that may help set it up:
https://docs.docker.com/engine/security/https/

(6) Investigate the server cert:
~/Documents/dockerexperiments/webofneeds/data/won-server-certs$ openssl x509 -noout -text -in t-cert.pem
Certificate:

========================
 other interesting things
======================================

Interesting part of the log:
owner_1            | 25-May-2017 19:35:01.759 INFO [localhost-startStop-1] org.apache.jasper.servlet.TldScanner.scanJars At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

Interesting part of the log:
java.util.concurrent.TimeoutException

Interesting part of the log:
Connection refused:

Interesting part of the log:
blue hard drive light on...perhaps the RAM is low and SWAP space is being used, perhaps there are memory leaks

Fix the certificate due to https://localhost:8890 unable to create resource errors?:

/home/brent/Documents/dockerexperiments/webofneeds/data/won-server-certs# cp *.pem /home/brent/.docker/

(will this really work? The "Protect the Docker daemon socket" has a secure by default section that says to set the DOCKER_HOST and DOCKER_TLS_VERIFY variables (setting DOCKER_TLS_VERIFY=1 in the .env file causes an error))

Change Log for PowerAqua (may 15th)

In /var/lib/tomcat7/webapps/poweraqua, change service_properties.xml from:

<?xml version="1.0" encoding="UTF-8"?><CONFIGURATION><PLUGIN_MANAGER>/var/lib/tomcat7/webapps/poweraqua/WEB-INF/aquaplugins</PLUGIN_MANAGER><REPOSITORY><SERVER>127.0.0.1:8080/openrdf-sesame</SERVER><PROXY></PROXY><PORT></PORT><LOGIN></LOGIN><PASSWORD></PASSWORD><PLUGIN_TYPE>sesame2</PLUGIN_TYPE><REPOSITORY_NAME>isp</REPOSITORY_NAME><TYPE>OWL</TYPE></REPOSITORY></CONFIGURATION>

(note, I might need to use localhost instead of 127.0.0.1)

Also in /var/lib/tomcat7/webapps/poweraqua/indexListInformation/indexbrentweb, change service_properties.xml from:

After running the shell script: /var/lib/tomcat7/webapps/poweraqua# ./createLuceneIndex.sh

the following log results:
https://gist.github.com/bshambaugh/d00017026e916d917030628c0ebec7b7

tl;dr: it helped a lot to put http in the server path before 127.0.0.1, so I avoid line 1152 "java.lang.IllegalStateException: unsupported protocol: '127.0.0.1'" in  https://gist.github.com/bshambaugh/c06f3b2b784f47e5a6e123df2ab42fed

./createLuceneIndex.sh also produced the following changes to the MySQL table:


But ontologyindextable is empty :( .

What I worked on Yesterday

I played with jQuery dialog boxes yesterday [1], thought about media queries to adjust the CSS grid layout, and read about scaling SVG documents [2] as well as button creation [3] so I can make my own scaleable [2] buttons.
