I will need to virtualize a jenkins software architecture and I don't know which architcture will be more efficient.

I need :

• a jenkins server
• an opensuse server for c/c++ 64 bits compilation
• an msys2 system for win32 compilation and packaging (windows system)
• an old 32 bits ubuntu 10.04 server for compilation.

willnorris/imageproxy is a caching image proxy server that we use in one of our deployments. We typically have a PHP backend that will serve some html or json to a client where the URL would be http://<imageproxy>/200/https://willnorris.com/logo.jpg. Then the client will fetch that image from the proxy. This is fine.

What I cannot get working is doing this in local development using Docker (Com ...

Short description

A Nomad / Consul cluster is running, with Traefik (with minimal configuration) as a system task on each Nomad client. There are 3 nomad servers, 3 consul servers, 3 nomad clients and 3 Gluster servers at this point. Set-up very similar to this article set on setting up a Nomad / Consul cluster

I'm trying to achieve rootless PHP-FPM pod running in Kubernetes.

I tried simply running process in Kubernetes pod via init script that does php-fpm -FO as www-data user but it complaints about not having permissions to access /dev/stderr (log output location). Adding www-data user to the tty group also didn't help.

I tried specifying another location like /proc/self/fd/2 and even /dev/pts/1 as log  ...

I have multiple and different dockerized applications, each one comes with its proper Nginx service which sends traffic to its containers based on some rules.

I need to put those applications on the same server, so I added a new Nginx in the host that will handle SSL, and forward the traffic to the correct dockerized Nginx.

Question: Is it ok to use Nginx in the host which will forward traffic to mu ...

I'm using Unbound DNS server as a resolver for my home LAN. It runs as a Docker container on the default bridge network and in general it works as I'd expect it to, except when trying to use it as a resolver for the other Docker containers hosted on the same machine.

I tried setting the nameserver in the containers' /etc/resolv.conf to the Docker host's LAN address, but this is clearly not the ri ...

I have the next environment: a cluster with a head node, which is used to access all the compute nodes and the storage nodes.

I would like to be able to launch docker processes using Slurm. With 'normal' d ...

recently, I have started to migrate a webserver with several apps to new server and bundling every app in a docker container. My current setup consist of nginx for reverse proxy and database servers running on the server itself and all web applications running in their own docker containers.

Am wrote a playbook to create a container within a host machine. my idea is to create multiple containers per hosts. am trying to use the host.ini file to divide the host machines as a group and each container as an Ansible host within the group.

To enable IPv6 in my docker setup, I've set this in the file /etc/docker/daemon.json:

{
"ipv6": true,
"fixed-cidr-v6": "2a01:xxxx:yyyy:zzzz/64"

I got the 2a01:xxxx:yyyy:zzzz from my ISP and found it via ip addr | grep inet6 | grep global.

My ISP keeps changing the zzzz bit, and it also changes when restarting the router.

I'm trying to set up a stack of services in Docker: Unifi, PHP, Nginx, and Certbot, where Unifi and PHP are the backend services and Nginx serves them in reverse proxy mode, while Certbot runs periodically to get SSL certs for Nginx.

I have it mostly working; all the GET requests work and I can view the page that Unifi serves. However, any and all POST requests via AJAX all throw a 403 error due  ...

I am in a weird condition with docker-compose that I cannot explain.

I have installed a docker-compose with three services to serve Symfony project. The services are php-fpm, mysql and nginx.

I've run out of ideas as to why I can't connect to this nginx inside or outside of the docker. I can understand that networking might cause a problem outside the machine, but even inside the docker nginx is not responding even though you can see it running and listening (inside the docker). Outside the docker, maybe the port isn't mapping thru but it seems to be configured such that it should.

I've been struggling for over a week to get a Windows container to run with an Azure App Service. My initial preference was to just use a standard container instance, but it appears that you only have the option of public or private networking, rather than custom (unlike with Linux containers). It looks like if you run your Windows container within an app service, you get the same networking options y ...

I just configured my server to multi-site revproxy using docker external network and configured my revproxy nginx container to work with fastcgi.
