Plan to compile web of needs with maven

Get Java Ready:

Download it:
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Install it:
https://docs.oracle.com/javase/8/docs/technotes/guides/install/linux_jdk.html#BJFJJEFG
(I suppose this means extract and move it)

https://www.cyberciti.biz/faq/linux-unix-bsd-extract-targz-file/
tar -zxvf {file.tar.gz}

Dynamic Link it:
ln -s /usr/lib/jvm/jdk1.8.0_121/bin/javac javac


Edit: Or try not downloading from the browser page...since you are using a headless server:
(https://stackoverflow.com/questions/10268583/downloading-java-jdk-on-linux-via-wget-is-shown-license-page-instead)

Get Maven Ready:

Download it:
wget  https://archive.apache.org/dist/maven/maven-3/3.3.3/binaries/apache-maven-3.3.3-bin.zip | sudo tee $(echo `md5sum apache-maven-3.3.3-bin.zip`)

Extract it:
unzip apache-maven-3.3.3-bin.zip

Move it:
cp -r apache-maven-3.3.3/ /usr/local/

/usr/bin/



Dynamic Link it:
cd /usr/bin
ln -s /usr/local/apache-maven-3.3.3/maven/bin/maven mvn

External (possibly unneeded) resources:
Install it:
http://maven.apache.org/install.html

Put together the web of needs with Maven:

Install git: sudo apt-get install git-all
(https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)


Clone the repository:
git clone https://github.com/researchstudio-sat/webofneeds
cd into the webofneeds/webofneeds directory

run: mvn install

If trouble is encountered see:
https://github.com/researchstudio-sat/webofneeds/blob/master/documentation/building-with-maven.md

and:
https://github.com/researchstudio-sat/webofneeds/blob/master/documentation/troubleshooting.md

Results without skipping tests (mvn install):

Question: Does won-docker need its own server cert, or does it  use the one created automatically by letsencrypt?++++++++++++++++++++

After confirming a security exception: https://won.strangled.net:8889/won/page/need/ resolves

4:05

(and it gives a Tomcat thumbnail icon)

(My guess is this security exception might be caused by a CN being set as strangled.net while the visited site was won.strangled.net ?  See this error: https://support.dnsimple.com/articles/what-is-common-name/ )

Notes for Experiments running Nginx in a Docker Container on Linode

Goal:

Get a Nginx Instance Running on Linode using a DNS alias:



(1) Get Nginx running.

Three ways to get Nginx on Docker:

Build it in with the Digital Ocean Tutorial (running Nginx on an Ubuntu Image):


https://www.digitalocean.com/community/tutorials/docker-explained-how-to-containerize-and-use-nginx-as-a-proxy


( & any Linode specific configuration??)

Pull a Docker image for Nginx from Docker Hub:
https://hub.docker.com/_/nginx/

Get the default Nginx page running:
sudo docker pull nginx
sudo docker run --name another-nginx -d -p 8040:80 nginx

Get a customized Nginx page running:sudo docker pull nginx
(does not need to be repeated, and the command below can be run concurrently)

Create index.html in /home/brent/Documents/dockerexperiments/nginx

docker run --name the-third -v /home/brent/Documents/dockerexperiments/nginx:/usr/share/nginx/html:ro -d -p 8030:80 nginx

or try a docker-compose script:
https://serversforhackers.com/getting-started-with-docker

Once you have an image built (or if you want to go back to what you have):

create index.html in /home/brent/share/
docker run -v /home/brent/share/:/var/www:rw -p 80:80 -d nginx-example

(2) Point it to a subdomain.

http://freedns.afraid.org/

Result of pulling from docker hub, getting the default Nginx running, and pointing the Public IP to a subdomain:

To do this locally with a particular file:

create index.html in /home/brent/share/
docker run -v /home/brent/share/:/var/www:rw -p 80:80 -d nginx-example

(check this:

docker run --name the-third -v /home/brent/Documents/dockerexperiments/nginx:/usr/share/nginx/html:ro -d -p 8030:80 nginx

I think it is to run an image from a container)

Subdomains, Linode, another hosting provider for the parent domain, and a third party DNS provider ...and all that

Trying to point a subdomain at Linode, where the hosting provider is Bluehost and the DNS registrar is name.com

Hosting SubDomains on Bluehost:

(set up subdomain on bluehost, and contact name.com to modify their zone file)

Then use NAT forwarding to point a docker container at the Public IP address for the hosting Linode Server

But using Bluehost and Linode for hosting and Name.com for parent DNS provision and Bluehost for subdomain provision adds a layer of complexity, What about https://freedns.afraid.org/ and Linode?
