When to use ” run ” or ” entrypoint ” in Docker?
I am not sure if it is a D-Bus problem or a docker one. Instead of using the “RUN” command, you should use the “ENTRYPOINT” one to run a startup script. You should use a startup script. The “run” command is executed only when the container is created and then stopped.
How to use Docker inside Docker with Jenkins user?
It’s quite likely that @carlossg is right about mixing container and host users and groups. Instead of mounting everything inside the Jenkins container, consider following https://docs.docker.com/engine/installation/linux/debian/ and building an image based on the Jenkins image but with Docker installed, i.e. by doing something like (untested):
Can a pipeline be run in the background in Docker?
Similar to the sidecar pattern, Docker Pipeline can run one container “in the background”, while performing work in another. Utilizing this sidecar approach, a Pipeline can have a “clean” container provisioned for each Pipeline run.
Can a docker Exec run as root in a container?
There’s the small risk that something breaks the entrypoint which starts as root, and there’s the risk that someone will docker exec to run a command as root in the container, but the more critical issue of a vulnerability of Jenkins resulting in a process running as root inside the container is eliminated. @sudo-bmitch Kinda what I was thinking.
How to communicate between two Docker containers by name?
To allow two Docker containers on the same host to communicate with each other by name: Create a user-defined bridge network: Create your own custom bridge network first using docker network create. Under the hood, Docker sets up the relevant networking tables on your operating system.
How to connect to Docker host from Docker container stack overflow?
Try docker run –net=host –rm -it hiromasaono/curl ping docker. If you see it’s pinging 127.0.0.1 then your configuration is wrong and you need to fix this line: hostip=$ (ip route | awk ‘/docker0/ { print $NF }’) . If it’s not 127.0.0.1 but the pings don’t succeed then your network setup is wrong or the hostip is wrong.
