Jenkins blueocean plugin with Docker

https://jenkins.io/doc/book/blueocean/getting-started/ and here the Docker installation instructions https://jenkins.io/doc/book/installing/#docker

Here all the Docker images https://hub.docker.com/r/jenkinsci/blueocean/tags/


Then I run this:

( http://devdocs.io/docker~1.12/engine/reference/commandline/run/index I am using Docker 1.12 )

docker run -u root -d -p 8080:8080 -p 50000:50000 -v jenkins-data:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock jenkinsci/blueocean

port 50000 is needed only if you plan to use slave build agents

(I had to remove --rm otherwise I get Conflicting options: --rm and -d )

docker ps gives you the containerid -> docker exec -ti 03e820715e74 bash

cat /var/jenkins_home/secrets/initialAdminPassword
copy and paste in localhost:8080 to unlock Jenkins

Witches' Sabbath with yum install and docker

After a major CentOS update, when I "oc cluster up" I get this:

Error: Minor number must not contain leading zeroes "01"

the usual "docker version mismatch" issue (go to hell OpenShift)

So I "yum install docker" and I get this:

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

I try "yum install docker --skip-broken" but I still get

Then I do yum list installed | grep docker

docker-ce.x86_64 18.01.0.ce-0.1.rc1.el7.centos @docker-ce-test

then "yum remove docker-ce.x86_64" and "yum install docker"


Installed:

Dependency Installed:

and everything works again.


I used to love Docker, but since it was split in CE and EE they messed really hard. Too much greed for money and need to place expensive consultants.
