Didn't know what was eating my diskspace after building a lot of images over night by CI/CD. With the command "docker system df" which I didn't know I just found 140 GB build cache. These files were not shown by ncdu. Thank you - very helpful!

I contemplated to add one more which is quite nice sometimes ```sudo truncate -s 0 $(docker inspect --format='{{.LogPath}}' nginx)``` to truncate docker logs (my example is to truncate the container name nginx).

Hallo Christian, thank for the video, is it possible to display the docker context in the shell prompt like for your computer "xcad on xmac at ~ docker context < docker context name >" ?

For some reason it doesn't work for me in starship, but i'll keep looking into it, if I find a solution

@DerTim 3 ай бұрын

Victor from DevOps Toolkit said once that you have an interest in keeping images small and recommended either alpine or using scratch and to use a sidecar container in kubernetes to debug. Is there a similar concept as a sidecar container in docker 🤔

Hi! Would you mind sharing where to find your animated wallpaper? Thanks for all your work. I've been learning a lot for your videos.

Hi Christian, another nice video! Could you maybe make a video about vulnerability management in Homelab? I am looking for a tool that scans all VMs / containers in my Homelab and shows me open vulnerabilities. I want to make my Homelab as secure as possible despite network separation. That would be great! Thank you!

@christianlempa 3 ай бұрын

Hm, that's an interesting topic, but I think I have to investigate more on this before I feel confident making a video.

I had seen the docker context command whilst glancing through available commands and assumed it was to do with the docker build context and didn't bother to dig into it. Now that I know what it's actually for (why didn't they call it "docker remote" a la git?) I 100% need it. That said, Synology run an old docker that doesn't have integrated docker compose yet, so not sure it will actually help me.

hey can you help me with something, If I have docker running on a mini pc, how can I have containers access my nas with r/w permissions?

@danielberglv259 3 ай бұрын

Without knowing exacly how your setup is and what you require, my way of doing this for containers like Syncthing, Jellyfin and such that require access to certain aspects of the NAS is to use NFS (Or you can use Samba, but NFS is better for this as it supports Linux permissions). Use autofs (works much better than fstab for this scenario) to mount what you need to a main location on your docker host and then just use regular mounts in your containers just like with any other consistent volume.

How do you make the command output goes down? Normally the previous command's output is scrolled up.

It's using the "input top (reverse mode)" setting in the warp terminal

Christian - Can you please do a new video on TrueNAS 23.10.2 and creating SMB shares? I cannot get this working from a Windows 11 PC. I can view and connect, but get "You don't have permissions." The UI has changed drastically and none of the old videos work when trying to create SMB shares on 23.10.2.

why does it suck? seems interesting to me, but sadly it doesnt work yet in my ARM Linux VM - i installed it on MacOS though, but i don't bother using it there :D

@frederickwood9116 3 ай бұрын

The free one runs out of answers (100 I think is the limit) It’s interesting and better than flipping back and forth to another tool. It’s not integrated onto the system in a way it can read the terminal output and possibly logs in real time and make suggestions about what’s happening or broken. You still have to ask it like any other ai tool currently.
