These steps were originally documented by mediatemple.net and I am copying it here for incase that source disappears on me.

STEP 1 - Add the user. In the following example, we will use the user name admin. The command adduser will automatically create the user, initial group, and home directory.

[root@root ~]# adduser admin
[root@root ~]# id admin
uid=10018(admin) gid=10018(admin) groups=10018(admin)
[root@root ~]# ls -lad /home/admin/
drwx------ 2 admin admin 4096 Jun 25 16:01 /home/admin/

Ran into a problem in VSCode recetnly with Lombok logging annotation causing a "log cannot be resolved" warning in VSCode.

Also, when running the project, as soon as that particular log.info line is hit, and exception is thrown.

First, I realized I didn't add the lombok plugin - so make sure that is installed.

I also opted to restart the Java language server when VSCode prompted me to do so.

Now, the log.info line was no longer "underlined" in VSCode, but the error still persisted... What was going on??

How to keep cluster connections cleanly separated

With time the .kube/config file will contain a mix of dev, test and prod cluster references. It is easy to forget switching off from a prod cluster context and make a mistake and run for example kubectl delete ns crossplane-system.

Direnv based setup

Use the following setup to avoid these kinds of errors and keep clusters separate.

Install direnv
