Docker Container is started but not runing - johnson267 - 02-27-2022
Following is my Docker compose file. I have used the Jenkins images to install Jenkins. Within the same file,I have defined another container from which I can SSH and connect with the Jenkins server.
Docker Compose File
version: '3'
services:
jenkins:
container_name: jenkins
image: jenkins/jenkins
ports:
- "8080:8080"
volumes:
- "$PWD/jenkins_home:/var/jenkins_home"
networks:
- net
remote_host:
container_name: remote-host
image: remote-host
build:
context: centos
networks:
- net
networks:
net:
Created another folder name Centos and created Dockerfile within it.
FROM centos:7
RUN yum -y install openssh-server
RUN useradd remote_user && \
echo remote_user:1234 | chpasswd && \
mkdir /home/remote_user/.ssh && \
chmod 700 /home/remote_user/.ssh
COPY remote-key.pub /home/remote_user/.ssh/authorized-key
RUN chown remote_user:remote_user -R /home/remote_user/.ssh && \
chmod 600 /home/remote_user/.ssh/authorized-key
RUN /usr/sbin/sshd-keygen
CMD /usr/sbin/ssh -D
I ran following command docker-compose build

then I ran following command docker-compose up -d
Output
[+] Running 2/2

When I run docker images, I can see remote-host
REPOSITORY TAG IMAGE ID CREATED SIZE
remote-host latest fcaaebf103d6 25 hours ago 367MB
jenkins/jenkins latest 97d23cbbfa56 5 days ago 463MB
but when I run docker ps, I do not see the running container.
