If you do a top on your Docker host, you may find a process for apache2 is PID 1234 but that is not the same as ID as in your container due to separation of processes and memory from the main host. Here is how you find the real PID within the docker container. On your host do this where 1234 is your PID. cat /proc/1234/status|grep NSpid NSpid: 1234 125172 ........

This is based off the LinuxServer Mastodon Image and Ibelieve this simplifies the bare basics of get things going because Mastodon is fairly complex but well worth the effort. WhyMastodon? For me, it's about having social freedom, when you use big tech there are MANYnegative things that happen. 1.) They tap and mine all of your data for profit. 2.) You have 0 privacy and 0 benefits (no possible profi........

After looking at several deployments of VMWare, we had one deployment where the company enabled balloon mode which is essentially a way to overcommit memory the hostnode(s) don't have. Let's say you have put your database into memory or use a cached service in Apache or haproxy/nginx. VMWare will start taking some portions of these and at some point it corrupts things and the application running will either crash, malfunction or segfault. Another factor is that OOMwill be........

If you are in an environment where you cannot use systemctl or otherwise kill apache, just do a manual graceful restart which does the same thing essentially without killing the process which may impact the service or container (eg. in Docker). apache2ctl graceful........

A lot of special characters and non-English will display as gibberish if you don't enable UTF-8 locale which is not done by default. An example of things you may see withoutUTF-8 ??~N?~[?

We know it is deprecated but there are still systems that are running Debian 8, or at least applications that used old packages such as PHP5 that you may need an environment to stage testing/updates for it.

Normally the first thing you would think is that you should use the host network in Docker but this loses the isolation, in that case I'd rather use LXC and a public IP or a full VM with public IP to avoid these issues. Before you Start I assume you have also ruled out any firewall issues on either end, that RTP or SIP signaling is not being blocked by either side. 1.) Key Settings in Docker/Ports Before starting, I assume you have forwarded........

nestybox is an alternative runc instead of the default containerd which is more hardened, efficient and secure. It even allows you to do a lot of things you normally couldn't without having privileged mode which is great for development and many other functions. However, the only drawback is that you must not have any docker containers already, if so you have to back them up / delete them before proceeding. Step 1.) Get the latest .deb / package:........

I doubt many people are doing this, but if you want an all Linux dev environment for Windows apps that you have made in Python, then you're probably using Wine, Python and maybe pyinstaller. The below error happened with pyinstaller and it has a lot to do with how Wine identifies paths/drives vs where you execute python.exe from Long-story short solution Never execute python commands from /root because that maps to Wine's default Z:, so any operations performed in /r........

Yes, even though Docker has no devices, we can still fool it well enough by passing through our X server info as a bind mount and setting our DISPLAY environment variable. Step 1.) Add Permission Grant permission to docker to use the xhost/xserver xhost +local:docker non-network local connections being added to access control list If you didn't do the above you will get an error like this when trying to launch a G........

In this quick tutorial we will deploy various AI models and compare the differences. We will be using smaller models so that most users should be able to follow this guide as long as they have at least 16G of memory and no other applications using much memory. In this tutorial we recommend that you use Docker to deploy ollama.........

Generally most containers are by default set not to start automatically. Ther eare 3 settings for the "RestartPolicy" of containers: no: Do not automatically restart the container (default). always: Always restart the container regardless of the exit status. unless-stopped: Always restart the container unless it is explicitly stopped. on-failure: Restart the container........

Although it is well-known that pptp is not secure and is subject to many forms of attacks, the reality is that a lot of legacy and embedded devices use pptp. I argue that if it is being used for routing or remote access or over an already secure connection (eg. another VPN like ikev2) then this is still acceptable. Or in a LANor in a public environment where no private data is exchanged. However, if the nature of the data is extremely sensitive, you should do whatever........

A lot of companies are unsure which solution to choose and many may not be aware of Docker Swarm as an alternative to Kubernetes. One thing that many Sysadmins find is that Docker Swarm is simply easier, quicker to setup and maintain by far than Kubernetes.........

If you have swarm services and dockerd is creating a high load even with the containers just being idle, the easiest solution is to upgrade to a newer docker version. For example an identical config of 3 nodes, with Redis 5 with 30 replicas produces a load of about 1.45 in Debian 10 with Docker18.09.1 If I create the same setup on Debian 11, with Docker 20.10.5+dfsg1 then the CPU usage is low. One other difference I wondered is the kernel. In my test setup........

We used a simple Debian 10 VM and showed the memory before starting docker and with no docker containers being started. The goal is to show much much memory dockerd actually uses. Before docker was started The VMwas using 58M of RAM. After docker was started it was using 99MB of RAM. How much RAM does docker use? It's not scientific but fair to say dockerd itself uses about 41MB of RAM (99-58).........

The issue is that Docker images are stripped down, so many tools and even python3 is missing, so you'll have to build or update the actual image yourself. I assume you have started an image with something like this and that you have the Nvidia Toolkit installed (assuming you are using GPUs). If you're not using nvidia just remove --runtime=nvidia --gpus all. docker run -it --runtime=nvidia --gpus all ubuntu bash These works for most images li........

This does not seem to be officially documented but makes sense that an overlay on an overlay does not work and is considered an unsupported filesystem as is even NTFS . Some admins/organizations try to use ecyptfs as a simple solution to encrypt the contents of Docker. Instead, you could probably........

Docker adds iptables rules that break a lot of things including MASQUERADE or anything that needs the FORWARD table. If NAT is not working after Docker installation, it is probably because it set the iptables FORWARD policy to DROP. This may also make you think that your br0 or bridge is not working, but it's likely just due to what we'll mention later on below, that, Docker probably set your FORWARD chain to default DROP all packets, so nothing on your bridge ever makes it out........

It sounds intuitive that you may just move the /var/lib/docker dir to another location and symlink it back but it won't work and you'll get an error. How to move Docker Storage the Correct Way This assumes that you want to use /mnt/raid as the new location. 1.) Stop Docker systemctl stop docker 2.) Move /var/lib/docker mv /var/lib/docker /mnt/raid/ 3.) Edit the Docker daemon file Specify the path you want........

This can be used on almost anything, since Gluster is a userspace tool, based on FUSE. This means that all Gluster appears as to any application is just a directory. Applications don't need specific support for Gluster, so long as you can tell the application to use a certain directory for storage. One application can be for redundant and scaled storage, including for within Docker and Kubernetes, LXC, Proxmox, OpenStack, etc or just your image/web/video files or even da........
