I am looking at keeping old images cleaned up from a VM that I have access to. I'm looking at keeping storage space minimal is because there is low hard disk space. Let's do this from a daily crontab.

Create a file in /etc/crontab.daily

nano /etc/crontab.daily/docker-prune

In the contents of the file we will insert the following.

podman system prune -af  --filter "until=$((30*24))h"

Allow the file to be executed.

chmod +x /etc/crontab.daily/docker-prune

NOTE: I use Podman instead of Docker but the command above is interchangeable in this instance.[...]

Adding an authentication middleware to my microservices in Golang using the HTTP Gin framework.

 func authMiddleware() gin.HandlerFunc {
	return func(c *gin.Context) {
		// Define the list of endpoints that require authentication
		securedEndpoints := []string{

		// Check if the current request path requires authentication
		for _, path := range securedEndpoints {
			if path == c.Request.URL.Path {
				// Check if the header exists and has the expected value
				headerValue := c.GetHeader("Authorization")
				expectedValue := "your_super_secure_password"

				if headerValue != expectedValue {
					// If the header value doesn't match the expected value,
					// return a 401 Unauthorized response
					c.AbortWithStatusJSON(http.StatusUnauthorized, gin.H{
						"error": "Unauthorized",

		// If the path doesn't require authentication, continue to the next handler

I ran into an interesting problem setting up PiHole on Podman. Pihole was not seeing the client IPS. This is due to how rootless containers work. Adding --network slirp4netns:port_handler=slirp4netns forwards the source address. After this, I enabled Pihole listening on all interfaces. I am now able to group devices and have different block lists. Do note that this is slower, don't use the slirp4netns network unless necessary.[...]
