Finding stories in everyday adventures
Ok, so out of a random urge to get a new version of mysql for my docker image which was showing last updated 12 months ago, I changed the Dockerfile build to use the latest version of mysql. This means that I would go from 5.7 to 8.x. Well, of course I thought it would be as easy as using mysql:latest, restarting the container and all my databases would magically appear, guess not! So, if …
So I just found out today that Cloudflare provides free HTTPS/SSL support. I’ve been using Cloudflare free account for many years and it works flawlessly. In fact this WordPress powered blog and my several other sites use Cloudflare services. With the addition of HTTPS/SSL, I can have added security.
This is most likely after effect of Spectre and Meltdown Kernel patches rolled out for CentOS. My OpenVPN container could not access /dev/net/tun device even though the Run Script had necessary parameters. Fix setsebool -P domain_kernel_load_modules=1
I recently started using Snapraid and Mergerfs setup to manage my disk pool. I have ~27TB of raw storage which I am managing. While setting up Mergerfs as usual ran into SELinux issues that will prohibit Docker and Samba access to the storage. So, here’s my fix. Samba setsebool -P samba_share_fusefs=1 Docker setsebool -P virt_sandbox_use_fusefs=1
SMTP Relay service allows you to use an external SMTP server to send your mails through.

Been containerizing a lot of my tools and just added phpMyAdmin to that list. It’s very easy to get going with it esp. if you also happen to have a Docker container running MySQL albeit with one minor issue. Official docker hub page: https://hub.docker.com/r/phpmyadmin/phpmyadmin/ Use an example Docker Run script below docker run \ –name name \ –restart=always \ -d \ –link mysqlcontainer:mysql \ -p localport:80 \ -e “PMA_HOST=mysqlcontainer” \ phpmyadmin/phpmyadmin localport is the port …
Found this awesome container that has Transmission with VPN support which I can use with Windscribe VPN.

Continuation of my previous post about fixing random Samba Share lockouts. I discovered that Docker and Samba were fighting to gain access to the folders. If I set the label to samba_share_t, then Docker loses access. If I allow Docker (with “Z” option while running container), then Docker resets the label to “svirt_sandbox_file_t”. How can I make both use it? Turns out there is a solution. Credit to this Serverfault post: https://serverfault.com/a/881098/449814 Create a new …
