Push docker image to Nexus - maven

Question

Hello I have Jenkins and Nexus on the same server. When Jenkins build project correctly, i want push image to Nexus 3, but every time i have the same problem (log below).
Configuration:
pom.xml
<nexus.url>http://adress/#browse/browse/components:docker-image</nexus.url>
<distributionManagement>
<snapshotRepository>
<id>nexus</id>
<url>${nexus.url}</url>
</snapshotRepository>
</distributionManagement>
...
<plugins>
<plugin>
<groupId>org.sonatype.plugins</groupId>
<artifactId>nexus-staging-maven-plugin</artifactId>
<version>1.6.4</version>
<extensions>true</extensions>
<configuration>
<serverId>nexus</serverId>
<nexusUrl>${nexus.url}</nexusUrl>
<autoReleaseAfterClose>true</autoReleaseAfterClose>
</configuration>
</plugin>
And i have file settings.xml:
<servers>
<server>
<id>nexus</id>
<username>login</username>
<password>password</password>
</server>
</servers>
Then i try "mvn clean deploy" and result is:
[INFO] Deploying remotely...

Every time is the same problem with 502 - Bad Gateway.
Do you have some proposal?

Unfortunately this will not work for a few reasons.
The URL you are using as a Nexus url is wrong, that URL is the browser URL. You need to use something more akin to https://nexusurl:portofdockerhostedrepo/repository/nameofdockerhostedrepo. You can get more information on setting up and pushing Docker images here: https://books.sonatype.com/nexus-book/reference3/docker.html#docker-push
Unless I'm completely wrong, mvn deploy is primarily for deploying maven artifacts into Maven repositories. I don't think this will work if you are attempting to deploy a Docker image. You might take a look at using something like this: https://github.com/spotify/docker-maven-plugin
Hope this helps.
