So far everything seems to be setup correctly, all of my arrs can see their necessary root folders, however, nzbget keeps throwing the following error when I attempt to download an episode of a show: Could not create directory /zfs1/series/MY FILE/_unpack: could not create directory : No such file or directory.

Subscribe to TechRepublic’s How To Make Tech Work on YouTube for all the latest tech advice for business pros from Jack Wallen.Hey guys total linux/docker/portainer noob here just trying to get nzbget and all the other arrs setup via portainer. Why you would use this will depend on your needs, but having this feature at the ready can be quite handy. You should see 1.0.0.1 and 1.1.1.1 listed ( Figure B).įigure B Our WordPress deployment is using the proper DNS entry.Īnd that’s all there is to defining DNS in your Docker containers. Once inside the container, view the DNS entries with the command: Open a new SSH connection to the hosting server (as the deployment won’t return your prompt) and then access the shell of the rabbitmq container with the command: Note: Without the network_mode option set to “bridge” the DNS entry will not work. In that file, let’s deploy a rabbitmq (an open-source message broker) container that will use a CloudFlare DNS entry, which will look like: With Docker Compose installed, you can now create the necessary file with the command: Sudo mv docker-compose-Linux-x86_64 /usr/local/bin/docker-compose Of course, you have to have this command installed, which can be done with the following: Now we’ll do the same, using Docker Compose. You should see the DNS server(s) you configured from the command line ( Figure A).įigure A Our Cloudflare DNS servers have been successfully configured.Įxit from the shell with the exit command. For that, access the shell of the container with the command: Let’s make sure the container honors our DNS configuration. You could also deploy that container with a primary and secondary DNS like so:ĭocker run -d -t -name ubuntuDNS -dns="1.0.0.1" -dns="1.1.1.1" ubuntu That command would be:ĭocker run -d -t -name ubuntuDNS -dns="1.0.0.1" ubuntu Let’s say you want to deploy a Ubuntu container, named ubuntuDNS, with the primary Cloudflare DNS server of 1.0.0.1. The first method will use the docker command and the second will be via Docker Compose. I’m going to show you how to deploy Docker containers with DNS pre-configured. How to deploy a container with DNS pre-configured
With those things at the ready, let’s deploy. You’ll also want to have a user that’s a member of the docker group (so you’re not deploying as either the root user or with sudo, both of which are a security issue). I’ll be demonstrating on Ubuntu Server 20.04, but the hosting platform doesn’t matter, so long as you have Docker running and can deploy containers. To make this work, you’ll need a machine running the Docker engine. So, what do you do? How do you define DNS for Docker containers, such that it won’t pick up the DNS of the hosting machine? There might be several reasons you don’t want your containers using the same DNS as their hosts. How to control the data funnel: Follow these 3 best practices

Say, for example, your host servers use a specific DNS server to prevent users from visiting particular sites. But what if (maybe for security reasons), you do not want your containers using the same DNS as your hosts. That may be fine and dandy for certain situations. When you deploy a container on your network, if it cannot find a DNS server defined in /etc/nf, by default it will take on the DNS configured for the host machine. Jack Wallen shows you how to configure specific DNS servers for your Docker container deployments.
