lxc | LXC - Linux Containers | Continuous Deployment library

I have a LXC CentOS 7 host running WildFly 21.0.2. The application server connects to a MariaDB 10.4.18 database using a two-way TLS connection (mutual authentication) and the MySQL Connector/J 5.1.47 JDBC driver. It worked fine until the upgrade from Java 8u282 to Java 8u292 that happened yesterday. The connection now fails with these errors:

I would like to do theses steps in a Jenkins pipeline:

1. Build a RPM (for CentOS) on a builder node
2. Create a new proxmox container from the master node (curl to call the PVE API)
3. Copy the built RPM from the builder node to the container node to test the yum install
4. etc.

The initial working code, from a terminal or a bash script was:

Recently i did install kubernetes using kubeadm on my old dual core AMD machine using bionic ubuntu and lxc. This is my lxc profile which i found in web:

Is there some method how can I define the major device (hdd, volume, ..) for LXC container?

I have separated disks for each service/project which I want run inside LXC container. But I couldn't find the way how can I specify storage for all files in the container. I mean whole container (/, /home, /var,...)

So finally I want to create this association 1 service/project == 1 container == 1 HDD

Is it possible?

i setted docker on ec2 and upload crawler scrapy code. since yesterday when i run ec2, it could collect data well. but suddenly now it doesn't work well. i guessed it is EC2 problem, because it could work well till today lunch time.

then i try to check EC2 condition, typed df -h, it showed

I am running Ubuntu 18.04 on the host and Ubuntu 20.04 inside LXC container. My goal is to run ROS2 (which requires Ubuntu 20.04) inside an LXC container, then use it to connect to two dynamixel servo motors and a USB Logitech webcam. I have also installed miniconda inside the container so that I can install OpenCV and dlib. I am also using conda virtual environment inside the container.

All the mentioned software works fine. Now I need to access the webcam with OpenCV, I use this command for testing

python -c "import cv2;print(cv2.VideoCapture(0).isOpened())"

which returns True on host but returns

The guides I have for deploying LXC on CentOS is to install snapd's lxd https://www.cyberciti.biz/faq/set-up-use-lxd-on-centos-rhel-8-x/

SnapD is a type of service that allows installing debian/ubuntu based packages with the logic being lxd is most up to date on that platform.

Well. I'm all open to installing an alternative version if it's easier to enable gpu passthrough.

Ultimately I'm trying to build a container environment where I can run the latest version of python and jupyter that has gpu support.

I have some guides on how to enable gpu passthrough.

I am using ubuntu 18:04 with an lxc / lxd steam container. It works great, I followed this tutorial and did some changes to the network stuff.

Steam works for opengl games but not for vulkan games. Same for lutris.

Host side:

I have been using LXC/LXD (4.0.4) for a while now and love the flexibility they provide - I however have started having some odd problems on my network. It seems the LXD is running a DHCP server and handing out address to other devices on my network.

I am running as a bridged network between the containers and the host computer and have assigned static address on the host machines as well as in the containers.

when i do a grep on DHCP on the host machine i see an LXD DHCP running and the address range that is being handed out to the other machines - as opposed to coming from the DHCP server i set up to address addressing.

Is there an easy way to disable the DHCP server, preferable through netplan or is there another method.

This problem is severely impacting my development as my test devices are getting the wrong IP assignments

Thank you in advance.
