Recommendations for YouTube playlists or books to learn VMware vSphere (Installation + Full Administration)

Hi everyone,

I’m looking for guidance and resource recommendations to learn VMware vSphere from scratch to administration level.

Specifically, I want to learn:

  • ESXi installation
  • vCenter Server setup and configuration
  • Networking (vSwitch, distributed switch basics)
  • Storage (datastores, iSCSI/NFS basics)
  • Cluster features (HA, DRS, vMotion)
  • Day-to-day vSphere administration

What I’m looking for:

I would really appreciate if anyone can suggest:

  • Good YouTube playlists (beginner → advanced)
  • Any structured courses or lab-based learning series
  • Any books worth reading (even if slightly older but conceptually strong)
  • Hands-on lab setups or home lab guides

I’ve seen a lot of scattered videos online, but I’m looking for something structured and practical, ideally covering a full vSphere environment end-to-end.

preventing other user from changing root password while having sudo

I’m setting up a Linux system user (devuser) with sudo privileges for basic system administration tasks, but I want to restrict them from changing the root password.

Here is my current sudoers configuration in /etc/sudoers.d/devuser:

Cmnd_Alias SYSOPS = /usr/bin/dnf, /usr/bin/systemctl, /usr/bin/journalctl, /usr/bin/ping, /usr/bin/curl, /bin/su

Cmnd_Alias PASSWD = /usr/bin/passwd

devuser ALL=(ALL) NOPASSWD: SYSOPS, !PASSWD

What I want to achieve:

  • Allow devuser to run basic admin commands (dnf, systemctl, logs, networking tools, etc.)
  • Prevent devuser from changing the root password using passwd root or similar methods

What I’ve tried:

  • Avoiding passwd in allowed commands
  • Trying to explicitly block it with !passwd, but it doesn’t seem working
  • Various sudoers configurations, but the restriction are not enforced

Any guidance or best practices would be appreciated.

I’ve been working as a Linux sysadmin for a while now .I want to start contributing to open source projects—but not just through application code. I’m especially interested in contributing from a sysadmin/DevOps perspective.

I’d love to hear from others who are already doing this:

  • How did you get started contributing as a sysadmin/DevOps engineer?

  • Are there specific types of projects that are more open to infra/ops contributions?

  • How do you identify repos that actually belong DevOps/sysadmin domain?

Any tips for making meaningful contributions without deep involvement in the core codebase?

Also, if you maintain or contribute to any projects that welcome DevOps/sysadmin contributions, I’d really appreciate recommendations.
