Can't access mapped port (can't connect from host to sshd running inside docker container)
By : Jan Boström

it should still fix some issue As mentioned in my comment, the -p switch on docker run will only route a port off of the Docker interface. For example you will have two interfaces, docker0 and eth0, you can route port 1200 from eth0 to port 22 on docker0. If you're connecting on the private interface docker0, there is no need to route external ports and you can just connect on port 22 (To the IP provided with docker inspect).

How to get my docker centos sshd passwordless server running?
By : parul gupta

around this issue You are trying to connect to you local ssh server instead of container. To connect to any port inside container, you need to expose and publish it and possibly map it to another one, especially in case when you want to run multiple similar containers on different ports on the same host. See Expose. So in your case your command should be code :
docker run -p 2222:22 -d sequenceiq/hadoop-docker:2.6.0
ssh -v localhost -p 2222
0.0.0.0:32799->2122/tcp
0.0.0.0:32800->2022/tcp

Docker nginx SELinux (centOS/RHEL) with 403 forbidden access
By : Sumit Khedkar
Date : March 29 2020, 07:55 AM
fixed the issue. Will look into that further Special circumstances related to old Docker 1.7.1 and RHEL6, means you gotta install RHEL7. SELinux does not work well with it. There are some core RHEL6 library issues (shared library permission errors) making it nearly impossible to use with Docker 1.7.1. The labels are all wrong. the processes inside the image are init_rc_t type labels which are incorrect. The files can be changed to httpd_sys_content_t but it doesn't work.

Is it possible to prevent RedHat/CentOS Docker host root access from within a container?
By : VARSHA SAHU

I hope this helps . If you are exposing your host's Docker socket to the container, then you've essentially given them root privileges to the host. If you are trying to provide an isolated Docker environment within a container, you should use Docker-in-Docker. See the dind tagged images for the docker image. This is how Play with Docker works.
