docker: connecting to localhost outside the container (intermediate) anthony explains

[@mrswats]

This is very interesting! This networking quirks is why I almost always use compose to run containers locally

[@fabiomanzo1800]

docker network inspect bridge --format='{{(index .IPAM.Config 0).Gateway}}'

[@ltn100]

Oh wow, I've been wanting to do this for a while and didn't think it was possible (at least, easily). Thanks!

[@ghost_7640]

Cool, is it possible to add more of the docker internal addresses? I am currently planning a project where i have 3 containers that i need for each one of them to have an internal ip address that could communicate with local hosts..

[@hrvojematosevic8769]

Did not know this about docker. Always glad to learn new things.

[@sebascm7278]

I ran into this problem and youtube recomended me this video.

[@theobotchway834]

I was actually researching on a network concept, and somehow this pops up 😂 Still answered my question tho

Thanks for sharing this information, have you ever tried zenoh communication between host and docker containers? Like zenoh pub sub ?

[@rafaelrosenberg260]

thanks for sharing this knowledge. I also was other here that struggled with this topic for some time. Your video was very helpfull. New follower of your content here =)

but what do i do if my app HAS to run 127.0.0.1 on my host? i could setup a proxy i guess. but another thing i cant do, when my docker is hosting a endpoint on port X, and i portforward 127.0.0.1:Y:X (host to docker) and i do a req to 127.0.0.1:Y, it doesnt work

[@namanrawal5849]

Interestingly, I can't seem to replicate this on macOS. I still get a connection refused running these exact same commands. I wonder if local firewall rules are disrupting the connection? Hmm

[@sgeisenh]

Are you still able to issue requests to localhost outside of docker even after you bind to the docker bridge network IP?

[@anthonywritescode]

you'd have to use the specific ip after that yeah -- since "localhost" is usually specifically 127.0.0.1

[@vipierozan99]

@@anthonywritescode can you do both? Like, on the same IP? Or maybe reroute traffic from one interface to the other? Example: I have 3 services on docker. I wanna start just one of them outside docker. And I don’t wanna change the config on the other 2 to have it all work.

[@clorzz]

I started trying to do the same in podman, and turns out host.containers.internal is just there by default.

[@nildesperandum2034]

Where do you open terminal? In docker? What about Windows users?? Thx

[@Fullflexno]

Thank you for this! Usefull!

[@RajatNair]

hey can you help me out i want to access the camera from docker jupyte lab so how can i do it.

[@samsal073]

Hi, Thanks for your video its very informative. I was wondering if you can help me with an issue I'm facing. I have enabled dockerdesktop host networking and inside the docker-compose I have created the loopback using extra_hosts: =host-gateway. The image Im using is for Apache Nifi and in Nifi you can specify the HTTPS_HOST to bind the application to , however I keep getting the error : java.io.IOException: Failed to bind

[@antoniofernandodiasjunior8896]

is there a way to get the access to loopback in linux instead of windows or macos? i think host docker internal does not work...

[@anthonywritescode]

that's....literally this video. it's recorded in linux

[@jcbrunhera]

You just save my day!! thks so much !!

[@bcodetube]

Can you use "docker run --network host" instead of bridge?

[@anthonywritescode]

rewatch the first 30 seconds or so

[@salmaindrianputri164]

How to do this with docker compose

[@anthonywritescode]

compose has settings for this, most of them match the name of the arguments I use. I don't use compose myself so you'll have to fill in the blanks there

[@RoyAAD]

Awesome
