Things won’t be as close to bare metal as they are in Linux. Because of this, you need to allocate CPU cores and RAM for the VM.
To make all this possible, a light Alpine Linux image is fired up underneath with xhyve MacOS native virtualization. It gives you the whole Docker API available from the terminal, even though Docker itself wasn’t created to work on Macs.

Almost.ĭocker for Mac is a pretty smart invention. I work at eBay Kleinanzeigen, one of the world’s biggest classified companies.Are you a Linux user who switched to Mac when you saw that Docker is now available as a native Mac app? Have you heard how great Docker is and want to give it a try? Did you think that you could just take your Docker Compose file, launch your project, and have everything work out for you? Well… you were right. If you liked it and felt the need to give me a round of applause or just want to get in touch, follow me on Twitter. You can check processes, files and operate like in your local environment.ĭocker attach is more restricted because it attaches your terminal’s standard input, output, and error to the main process of a running container. To connect to a container using plain docker commands, you can use docker exec and docker attach.ĭocker exec is a lot more popular because you can run a new command that allows you to spawn a new shell. To be able to detach without stopping the container, you can attach to the container by disabling forwarding signals: # start the container againĭocker run -name nginx -rm -p 8080:80 -d nginxĭocker attach -sig-proxy=false nginx Conclusion ^ 1#1: signal 2 (SIGINT) received, exitingĭetaching can be tricky because control + c is also used for detaching. So if you press control + c, which triggers a kill signal, your container will shut down. While running this, you can open Because the container prints access logs on each page opened, you will see the output in your terminal.Īdditionally, input is forwarded as well to the container.
In practice, this means everything you enter gets forwarded to the container, and everything that is printed will be shown in your console. Method 2 – Attach to a Running Container using docker attach The docker attach command attaches your terminal’s standard input, output, and error to a running container using the container’s id or name. If you use Kubernetes, an ephemeral container feature allows you to debug containers without a shell as well as crashed containers. For example, distroless containers are getting more popular to reduce the footprint of the container. Therefore, there is no way to get a shell in that container in a plain docker Universum and you can not start any shell.ĭepending on your container orchestration tool, you might still be able to access the container. Also, there might not be a shell installed in the container. In case you can not start bash, you can try starting a sh-shell: docker exec -it nginx sh It can happen that your container does not have bash installed. -it combines -i and -t, which allows you to interact with the process.$ docker exec -it nginx can exit the current shell by pressing control + d or typing exit. # create and connect to a bash shell in the container $ docker run -name nginx -rm -p 8080:80 -d nginx It runs a new command in the container, which allows you to start a new interactive shell: # start a container The most common and helpful command for getting a shell in a container is docker exec -it. Method 1 – Attach to a Running Container using docker exec This article will describe different methods for doing so along with their constraints.

Knowing how to SSH into a container is essential to using, debugging, and operating containers on your local operating system or remote setup. And the most popular container technology is called Docker. Containers are the bread and butter for running applications today.
