OE:
BUSYBOX vs BUSYBOX:1.28
Something I had noticed when doing the course but which I think wasn’t explicitly mentioned (I’m not sure), is why you use busybox:1.28 instead of the latest version of busybox when troubleshooting and using tools like nslookup
So I asked myself, why? After a little digging, I ran into this - https://github.com/docker-library/busybox/issues/48
So it looks like this is due to a upstream change in nslookup in busybox. So remember to stick to busybox:1.28
