![]() But if I have stopped that container, then the name isn't in use, is it? What does this mean and how can I run both the NordVPN container and the qBittorrent container, as well as route all qBT traffic through the VPN container? And how can I test whether the traffic is actually being routed through the VPN container?Īnother problem I seem to have is that even though I have stopped a few containers, I can't restart them under the same names as the old one, under the grounds that that name is already in use. The error I get is the following: ERROR: for qbittorrent Cannot create container for service qbittorrent: conflicting options: port publishing and the container type network modeĮRROR: for qbittorrent Cannot create container for service qbittorrent: conflicting options: port publishing and the container type network modeĮRROR: Encountered errors while bringing up the project. I can run the qBittorrent container using standard docker run like so: docker run -d -p 8080:8080 linuxserver/qbittorrentīut when I try and paste the following into my docker-compose file to allow it to work with the VPN container and a few other services, I get a error: qbittorrent: My problem is that I have downloaded both the linuxserver/qbittorrent image and the bubuntux/nordvpn image from the Docker repository, and I am trying to run both of these using a docker-compose file. You need to ensure you did the configuration right, or you can get hacked.I know that there's already a post on a similar topic to this, but I'm having a slightly different problem to them. it isn't simply download image and push it for docker to simply work like that. Instead containers should be on a user-defined network and not the default “docker0” bridge.īy now i think you get the idea. Don’t use the default bridge “docker0.” Using the default bridge leaves you open to ARP spoofing and MAC flooding attacks. Don’t use docker exec command with privileged or user=root option, since this setting could give the container extended Linux capabilitiesĢ5. To preserve the immutable nature of containers – where new containers don’t get patched but rather recreated from a new image – you should not make the root filesystem writable.Ģ4. Any changes made to the root filesystem will likely be for a malicious objective. Once running, containers don’t need changes to the root filesystem. Set the container’s root filesystem to read-only. As a general rule of thumb, ensure only needed ports are open on the container.Ģ1. By default, Docker maps container ports to one that’s within the 49153 - 65525 range, but it allows the container to be mapped to a privileged port. Don’t map any ports below 1024 within a container as they are considered privileged because they transmit sensitive data. By default, the ssh daemon will not be running in a container, and you shouldn’t install the ssh daemon to simplify security management of the SSH server.ġ8. Don’t mount sensitive host system directories on containers, especially in writable mode that could expose them to being changed maliciously in a way that could lead to host compromise.ġ7. By default, containers run with root privileges as the root user inside the container.ġ6. As a best practice, run your containers as a non-root user (UID not 0). Secure all Docker files and directories (see 4.2 above) by ensuring they are owned by the appropriate user (usually the root user) and their file permissions are set to a restrictive value (see the CIS benchmarks section on Docker daemon configuration files).Ĩ. ![]() What follows is a list of best practices derived from industry standards and StackRox customers for securely configuring your Docker containers and images.Ĥ.
