4. Run the nexus container

Docker run-id-- privileged=true-- name=nexus3-- restart=always-p 8081 purl 8081-v / wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3

Console output

[root@xxx] # docker run-id-- privileged=true-- name=nexus3-- restart=always-p 8081 purl 8081-v / wandou/nexus3/nexus-data:/var/nexus-data sonatype/nexus3980f3759783f3ba7e59302848f816e371b229957f2c12b8f92934d468e061b00

Explanation:-id creates guardian container-privileged=true grants root permission (mounting multi-level directory must be true, otherwise the container has insufficient access to host)-name= name gives your container a name-p host port: container port mapping-v host directory: container directory mount here it takes some time to start and access nexus depending on the machine configuration. To access nexus3, please make sure that the 8081 port of the server (depending on the port configured when running the nexus container above) is open in the security group! Browsers visit http://ip:8081 6. After logging into the nexus3 page, there is a login button in the upper right corner that clicks to show the login box nexus3. The default account number is still admin, but the password has changed. The specific password is stored in the admin.password file in the nexus-data path of the nexus3 container: 1.
