Docker Get Host Ip Mac Instead Of

By Ryan Sukale November 8, 2016. If you need to use the ip address of your mac instead of using localhost, here is an easy way to find the ip address of your mac via the command line. Just run the following command in your terminal. In the output that follows, the place that I have marked as ip address is your. A few days ago I noticed that my docker services use my hosts default IP when talking to other internet applications.

Even if disk IO looks ok on Docker Desktop for Mac, it is not even close to native performance.I really like the idea of WSL2 with dynamic CPU and memory allocation with Hyper-V but not sure how efficient the file syncing between Windows and Linux Subsystem is.Because I use PHPStorm which is very good at indexing and finding stuff, I need to access the files from both Linux subsystem and Windows. VSCode seems to be another option which is WSL2-friendly but I hear people switching back to PHPStorm from VSCode because it's not that advanced for PHP development yet.Is there anyone who compared the Docker on WSL2 with the Docker Desktop for Mac so far?Wow this is the first time I hear something good about WSL1 IO performance.It's because Docker Desktop is doing the real work here. It's just a Docker volume from a Windows mounted drive into the Docker Desktop VM.WSL 1 is really doing nothing except allowing the Docker CLI / client to talk to Docker Desktop after doing a bit of configuration. I wrote about how that's set up here: There's thousands of people on Windows taking my Docker course and no one with this set up has contacted me yet saying the performance was bad once they've disabled Windows defender, where as I've had a bunch of people on MacOS mentioning poor volume performance with Docker Desktop (not everyone but some).In theory WSL 2 should be even better because WSL 2 can be used as a back-end and your code would be living directly in WSL 2's file system instead of in a mounted drive.

Scroll down or skip to note for macOS.Main idea: pass in the docker0 IP address to the container via -add-host:Get the host machine's address for the docker0 interface and put it in shell var (note that docker0 doesn't exist on macOS, scroll to the next part if you're on a Mac). CLI: Using the -add-host parameter with docker runIf you're on macOS using Docker Desktop, it's easier. I'll show it here in two ways, one via CLI and one via docker-compose as a bonus. Docker provides a way to add hosts into your container's /etc/hosts file.

Docker-compose:This mechanism also available docker-compose.yml files as the extra_hosts key, like so:And since we took advantage of variable substitution in CLI example, I'll show how we can do the same here: version: '2'In this example, we don't have an. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.The gateway is also reachable as gateway.docker.internal. From 18.03 onwards our recommendation is to connect to the special DNS name host.docker.internal, which resolves to the internal IP address used by the host. # In my macOS:$ :~$ docker run -it busybox /bin/shPING docker.for.mac.localhost (192.168.65.2): 56 data bytes64 bytes from 192.168.65.2: seq=0 ttl=37 time=0.420 ms64 bytes from 192.168.65.2: seq=1 ttl=37 time=0.564 ms- docker.for.mac.localhost ping statistics -2 packets transmitted, 2 packets received, 0% packet lossRound-trip min/avg/max = 0.420/0.492/0.564 msPING host.docker.internal (192.168.65.2): 56 data bytes64 bytes from 192.168.65.2: seq=0 ttl=37 time=0.289 ms- host.docker.internal ping statistics -1 packets transmitted, 1 packets received, 0% packet lossRound-trip min/avg/max = 0.289/0.289/0.289 msPING gateway.docker.internal (192.168.65.1): 56 data bytes64 bytes from 192.168.65.1: seq=0 ttl=37 time=0.265 ms64 bytes from 192.168.65.1: seq=1 ttl=37 time=0.625 ms- gateway.docker.internal ping statistics -Round-trip min/avg/max = 0.265/0.445/0.625 msThe host has a changing IP address (or none if you have no network access). Additionally, you can also now also use gateway.docker.internal to access the host's gateway. Instead, you can actually simply go into the container and use a special macOS-only DNS name ( docker.for.mac.localhost) that comes out of the box (version 17.06+):Update April 2019: The DNS name is now called host.docker.internal in the docs, though docker.for.mac.localhost works just as well for now in Docker 18.09.3.

And if it is please let me know so I can write more! You can always find me on Twitter. Since we didn't name the container, we grab the container ID using docker ps first, which is 0dde138913ee: :~$ docker exec -it 0dde138913ee /bin/shAnyway, hope this is helpful in some way. To become an env var, we need export it first, and then run docker-compose: $ :~$ export HOST_IP=$HOST_IP & docker-compose up -dNote: I don't run it as sudo here, but remember that sudo won't work with export!The -d flag runs it in the background, and we can go into the container and check out our /etc/hosts file in almost the same way as we did earlier.
