yum update hung due to loading lots of plugins

-
After adding my new repository, yum update takes forever to finish:

# yum update
Loaded plugins: aliases, changelog, downloadonly, fastestmirror, filter-data, keys, kmod, list-data, protect-packages, protectbase, rhnplugin, security, tmprepo,
              : verify, versionlock


I noticed yum loading lots of plugins, so I disabled the yum plugins and issue resolved:

# cat /etc/yum.conf |grep plugins
plugins=0

Rebuild your new Yum repository after changing the packages

-
If you have done any  changes  to your local  repository  packages, adding new ones or deleting some, you can just simply update your yum sqlite metadata database for your changes to take effect, rather than creating the whole repository again which takes time if you have  thousands  of packages in your repository.  Here is how we rebuild our yum repository. 1. After you are done with adding/removing packages to your local repo, then: # createrepo --update /path/to/repo_dir 2. On the  client  side, you need to clean up the cached yum meta data in order to see the changes after repo rebuild: # yum clean all 3. Now update the  client  yum cache  # yum update

Running Docker Wildfly/JBoss Application Server in Debug mode via Eclipse

-
I have recently built the whole Development Environment of Java Enterprise Edition (J2EE) project on multiple Docker containers. It has saved the hassle of setting up a dev env for new developers. All it takes to setup the environment is to clone our github repositories and run the Docker images. I will explain the setup in a future post. Build Wildfly Docker Image with Debugging Enabled So basically in order to run the Wildfly in debug mode, we need to add --debug  flag to the Wildfly standalone.sh  startup script. Also we need to expose port 8787  in our image as it's the default port for Wildfly JVM debug mode. 1. Create or change your Wildfly Dockerfile as follows: $ cat Dockerfile FROM jboss/wildfly: 10.0 . 0 .Final EXPOSE 8787 CMD [ "/opt/jboss/wildfly/bin/standalone.sh" , "-b" , "0.0.0.0" , "-bmanagement" , "0.0.0.0" , "--debug" ] 2. Build and tag the image: $ docker build -t wildfly-debug . 3.
