I am behind a corporate proxy. I have HTTP_PROXY, HTTPS_PROXY, and NO_PROXY set in the image. When I'm connected to the network I have access to a private npm registry that is on this intranet. My docker image is unable to access this registry.

On the host machine, a mac, I can run:

curl https://<registry>/nodejs/content/groups/npm/lodash

And I get the JSON for the package.

On the docker image I run the same command and I get this:

curl: (35) error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

When I npm install with the registry set it also returns the same issue.

Why can't docker access the same endpoint that my host machine can? How can I enable it to?

Try using the host's network. If you are able to access that URL from your local, then it should work. You just need to add the --network host argument to your build/run command.

Example:

$ docker build <all the other args> --network host .
$ docker run <all the other args> --network host .

Docker creates a bridge network by default but you can force it to use your local network with --network host arg.

Can't access server on LAN from container · Issue #231 · docker/for , Can't access server on LAN from container #231 Is it because the subnet of my laptop (docker host) is 172.17.22.1/24 so it conflicts with docker's one? Our network configurations has changed since so I can't test this  The problem is you can’t access the service websites from the Docker for Windows host. Docker for Windows creates a private network for itself in Hyper-V. Both the Docker host and containers are issued IPs in this private network. By default, the computer running Docker for Windows cannot access this private network.

A bit late but it migh thelp someone. I had the same problem and my solution was configure docker daemon to use my intranet DNS

Edit the daemon.json file

sudo vim /etc/docker/daemon.json

The file should look something like this

{
  "dns": ["ip-here", "ip-here"]
}

Restart de daemon

sudo service docker restart

How to access containers by internal IPs 172.x.x.x · Issue #221 , So by default you can not connect to containers. my dev machine would be also a docker host, I could access docker internal network 172. I cannot access the service this way. But if I get the IP address of the container's nat connection, I can access the service in the container. The Docker HealthCheck (inside the container) is making requests agains the service as well and those are passing. So it's something in the connection between the host and the container.

I encountered a similar issue, which was there is a docker network created by some compose file remains there

docker network ls

I removed the danging one and retain the intranet access

How to access docker container from another machine on local , I can access it through the specific container IP, but noone else can access So now others on your network can access port 80 of your host to hit port 80 of container. but I cannot find a document that simply explains how to do the following:. Then you need to get its IP. Suppose it is default bridge network, so: docker network inspect bridge (usually something like 172.17.0.2) Try to ping this IP from windows machine ping 172.17.0.2. If you where on linux ping would work out of the box. On docker for windows it doesn't work out of the box.

Cannot connect to the internet from your Docker containers?, The good news is that you can clearly verify that something is just wrong with Docker by simply pinging google.com from your host and a simple  Go to Start, type "Internet Options" then then the Security Tab, then click Local Intranet, then Sites.

Docker containers can't resolve DNS on Ubuntu 14.04 Desktop Host , So if the host's /etc/resolv.conf is wrong, then so will the docker container.

Docker containers have an internal network and each container is associated with an IP address that can be accessed from the Docker host machine. Being internal IP, this IP cannot be used to access the containers from external network. But the Docker host machine’s main IP is accessible from outside. For a webserver application, you’d obviously need to enable user access to it from the external network. So, the solution we use is to bind the internal port 80 of the Docker container to a

Docker Tip #29: Containers Can't Access the Internet? Check , Docker can run on most major platforms but this tip is focused on running Docker on a Linux host, and will most likely only apply to production  To access from the outside world we need to bind ports while starting a container so that it will create an IPtables masquerading rule which allows the outside world to access the container. Now let us bind the port (8080) from Docker host to container port (80), By doing a bind we can reach the webserver running on the container. While
