Boot2Docker is a small Linux VM running on VirtualBox. So before you can use your files (from Windows) in Docker (which is running in this VM), you must first share your code with the Boot2Docker VM itself. To do so, you mount your Windows folder to the VM when it is shutdown (here a VM … Read more
Docker by default supports 3 networks: 1) None: This mode will not configure any IP for the container and doesn’t have any access to the external network as well as for other containers. It does have the loopback address and can be used for running batch jobs. # docker run -it –network=none ubuntu:14.04 /bin/bash root@66308c6686be:/# … Read more
Yes you can add same location as a volume to many docker containers. Additionally you can use –volumes-from to mount your log directory in one container not actually running any application and then use the volumes from this container in your other containers without having to repeat the paths everywhere. Worth a read Docker volumes
As answered here there is a software solution for this, called DNS Proxy Server. $ sudo ./dns-proxy-server $ docker run –rm –hostname nginx.dev nginx $ ping nginx.dev PING nginx.dev (172.17.0.4) 56(84) bytes of data. 64 bytes from 172.17.0.4 (172.17.0.4): icmp_seq=1 ttl=64 time=0.043 ms 64 bytes from 172.17.0.4 (172.17.0.4): icmp_seq=2 ttl=64 time=0.022 ms
Maybe you have already found that Docker (aka Moby) internally uses libnetwork to configure and enable the embedded DNS resolver. Libnetwork binds the resolver to the container’s loopback interface, so that DNS queries at 127.0.0.11 can be routed (via iptables) to the “backend DNS resolver” in the Docker Engine. See the libnetwork type and the … Read more
According to talks on Docker for windows Github issues (https://github.com/moby/moby/issues/31604), when Docker for Windows is run under Windows 10, it is actually using a Hyper-V isolation model (and process model is not accessible in Win 10 scenario). And in that isolation type, your container is run inside a lightweight VM, which DOES have a default … Read more
After discovering that this is massively undocumented,here’s the correct way to mount a NFS volume using stack and docker compose. The most important thing is that you need to be using version: “3.2” or higher. You will have strange and un-obvious errors if you don’t. The second issue is that volumes are not automatically updated … Read more
Links have been replaced by networks. Docker describes them as a legacy feature that you should avoid using. You can safely remove the link and the two containers will be able to refer to each other by their service name (or container_name). With compose, links do have a side effect of creating an implied dependency. … Read more
i don’t know much about chromium, but, I did work with X way back when 🙂 When you tell an X client to connect to :0, what you are saying is connect to port 6000 (or whatever your X server runs on) + 0, or port 6000 in this case. In fact, DISPLAY is IP:PORT … Read more
