After starting a Sonatype Nexus 3 image (command 1) I tried to create a repo and push one test image (command 2) to that repo but got an error 405 (error 1)
command 1
$ docker run -d -p 8081:8081 --name nexus sonatype/nexus3:3.14.0
command 2
$ docker push 127.0.0.1:8081/repository/test2/image-test:0.1
error 1

Nexus Repository supports Docker images and Helm 3 repositories with Proxy, Hosted, and Group repositories, allowing users advanced container management capabilities across development teams.
After some research I found out that the nexus3 docker repositories are designed to work with individual port for each repository (hosted, group or proxy).
https://issues.sonatype.org/browse/NEXUS-9960
So I destroyed my previous docker container because I didn't have any relative info on it and launched the same command but with an extra port enabled.
$ docker run -d -p 8081:8081 --name nexus sonatype/nexus3:3.14.0
Updated: need to open port 8082 for docker
$ docker run -d -p 8081:8081 -p 8082:8082 --name nexus sonatype/nexus3:3.14.0
So when you make a new docker repository you need to define at least a http connector port, that I defined in the image as 8082.
After that you have to login to the service with the default admin account (admin admin123)
$ docker login 127.0.0.1:8082
Username: admin
Password:
WARNING! Your password will be stored unencrypted in /home/user/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store
Login Succeeded
Then tried to upload the new tag to that url and it wworked.
$ docker push 127.0.0.1:8082/repository/test2/image-test:0.1
The push refers to repository [127.0.0.1:8082/repository/test2/image-test]
cd76d43ec36e: Pushed
8ad8344c7fe3: Pushed
b28ef0b6fef8: Pushed

So because I needed to create a custom nexus3 docker image for my production environment I started the Dockerfile like this:
FROM sonatype/nexus3:3.14.0
ENV NEXUS_DATA = /nexus-data/
EXPOSE 8090-8099
I will be using the ports from 8090 to 8099 to specify different docker image repositories instead of 8022, but in case I needed more ports I could just change the valors or add a new range of ports.
Hope it was useful!!
