Work Experience
DevOps Engineer
strogo pro
- Created an OpenVPN setup where each client would have his own personal IP and iptables rule; used Bash script for adding new users which would send a password-protected archive to the client along with "How to Configure VPN" instructions. The passwords would be sent through a different channel.
- Deployed GitLab inside Docker (with volumes for permanent storage); created web hooks that would trigger Jenkins jobs on "git push."
- Created an environment for easy Docker deployments—SQL database with hostnames, service names, versions, container parameters, and more which would be used in a Jenkins job.
- Wrote a Bash script for Check_MK which would scan for Docker containers in a "Restarting" mode and report to Slack with the hostname, service name, and logs for that container.
- Created an environment for multiple customers on a server utilizing LXC with a NGINX proxy in front of them.
