We don’t really need the Redhat containers, we build our own just fine. But just for the reference here’s some left-over documentation on that front.
Fetch and upload those to the root dir of the Atomic Host,
==> /root/
Write down the IP of docker0,
ifconfig docker0
Extract, modify (remove RHEL specific shit) and build the containers,
cd ~/
mkdir centosdb/
mkdir centosweb/
tar xzf mariadb_cont_2.tgz -C centosdb/
tar xzf web_cont_3.tgz -C centosweb/
cd ~/centosdb/
vi Dockerfile
FROM centos:latest
RUN yum update -y
#RUN yum-config-manager...
RUN yum -y install net-tools mariadb-server
cd ~/centosweb/
vi Dockerfile
FROM centos:latest
RUN yum -y install deltarpm yum-utils
#RUN yum-config-manager...
RUN yum install httpd procps-ng MySQL-python -y
vi action
con = mdb.connect(os.getenv('DB_SERVICE_SERVICE_HOST','172.17.0.1'), 'dbuser1', 'redhat', 'gss')
Build and run the database container,
cd ~/centosdb/ docker build -t centosdb . cd ~/ docker run -d -p 3306:3306 --name=centosdb1 centosdb
check that the db service responds,
nc -v 172.17.0.1 3306
Build and run the web container,
cd ~/centosweb/ docker build -t centosweb . cd ~/ docker run -d -p 80:80 --name=centosweb1 centosweb
check that the web server works,
nc -v localhost 80 curl http://localhost/index.html check that the application works, curl http://localhost/cgi-bin/action
