I'm using docker-desktop (version: Docker version 20.10.12, build e91ed57) on macOS

My problem: Can not connect and push image to the nexus registry container

Here is my steps & errors:

1. Pull & Start nexus container

   docker volume create --name nexus-data

   docker run -d -p 8081:8081 --name nexus -v nexus-data:/nexus-dasonatype/nexus3:3.37.3

2. Connect to the 0.0.0.0:8081

Then i connect to the 0.0.0.0:8081 and create a docker-hosted repository and in HTTP section i add the 8083 port.

then i create a user (ali) and assigned to it a password and a role

3. add insecure-registries to the docker engine

then according to this documentation i added this line to the docker engine:

"insecure-registries": ["0.0.0.0:8083"]

4. restart the docker and container
5. try to login

then i tried to login via this command:

docker login 0.0.0.0:8083

but it return an error:

Error response from daemon: Get "http://0.0.0.0:8083/v2/": dial tcp 0.0.0.0:8083: connect: connection refused

Why i get this error?!

i tried many things to solve my problem including:

• Open port 8083 on my machine
• add the 0.0.0.0 to my host file
• open port 8083 on my container too

but nothing works at all!

what should i do?!

CodePudding user response：

To access a port in the container from the host, it needs to be published. So the run command should be

docker run -d -p 8081:8081 -p 8083:8083 --name nexus -v nexus-data:/nexus-dasonatype/nexus3:3.37.3
