Connect to container from another container or host using the same name


Connect to container from another container or host using the same name

it should still fix some issue You cannot configure your containers for something like that, but you can configure your host.
If you are on Linux or MacOS add an entry to /etc/hosts that maps postgresql to localhost. Something like:
code :
127.0.0.1  localhost postgresql

wish help you to fix your issue The -link parameter isn't supported on groups, only on single containers. With -link, if the linked-to container goes away (i.e. crashes or redeployed) and is replaced by a new instance, you need to redeploy the linked-from container (in this case group) as well, increasing chance of overall failure.
I think the intention is to use something like service discovery/service proxy (now deprecated in favor of amalgam8.io) so that, if the linked to container/service has to be replaced, you don't have to redeploy the whole group as well - the new one will automatically be picked up as the new instance of that microservice.

Any of those help There is indeed no limit on a container per default, but there is a large amount of flags allowing you to control a container behaviour at run time.
code :
docker run -it --cpus="1.5" --memory="1g" ubuntu /bin/bash

like below fixes the issue With a default execution of an image, the answer is a conditional no. The kernel capabilities are limited, the filesystem is restricted, the process space is isolated, and it's on a separate bridged network from the host. Anything that allows access back to the host would be a security vulnerability.
The conditional part is that it can use up all your CPU cycles, it can exhaust your memory, it can fill your drive, and it can send network traffic out from your machine NAT'ed to your IP address. In other words, by default, there's nothing preventing the container from a DoS attack on your host.

hop of those help? On docker for windows you can use address 10.0.75.1:8080 but you need to configure your firewall, a better way is using address 10.0.75.2:8080,
for both addresses you have to publish your port when you run container

around this issue To my surprise, it was actually a firewall issue in my case.
Update/Enable the tcp port [2375] on the docker host machine fixes the issue.
