Question I made the mistake of installing Docker via Snap... Once I realised that snap hadn't permissions to run in my working directory (on a different partition), I removed it. Now I can't use docker after I've installed it via apt-get. Please help. I've done sudo snap remove docker but when I sudo apt install docker and run via docker, I get bash: /snap/bin/docker: No such file or directory Answer I had the same problem.…

Question Docker works great on a Mac for me, but I have to run docker host inside of a VirtualBox (or Parallels, or VMWare Fusion), since Mac's kernel doesn't support docker. So I tried to setup my application and a docker-compose on an Ubuntu Desktop - natively, where both docker client and docker host run physically on the same system. This worked, but my running docker containers can't write into a mounted host volume.…

Question I can't seem to find a compiler/plugin for mono. Does one exist?

Question Below is a upstart script for redis. How to I create a pid so I use monit for monitoring? #!upstart description "Redis Server" env USER=redis start on startup stop on shutdown respawn exec sudo -u $USER sh -c “/usr/local/bin/redis-server /etc/redis/redis.conf 2>&1 >> /var/log/redis/redis.log” Answer If start-stop-daemon is available on your machine, I would highly recommend using it to launch your process. start-stop-daemon will handle launching the process as an unprivileged user without forking from sudo or su (recommended in the upstart cookbook) AND it also has built in support for pid file management.…
