To expose just one port, this is what you need to do: docker run -p <host_port>:<container_port> To expose multiple ports, simply provide multiple -p arguments: docker run -p <host_port1>:<container_port1> -p <host_port2>:<container_port2>
You can run an interactive shell container using that image and explore whatever content that image has. For instance: docker run -it image_name sh Or following for images with an entrypoint docker run -it –entrypoint sh image_name Or if you want to see how the image was build, meaning the steps in its Dockerfile, you … Read more
I’m also interested in this problem. As @Thasmo mentioned, port forwardings can be specified ONLY with docker run (and docker create) command. Other commands, docker start does not have -p option and docker port only displays current forwardings. To add port forwardings, I always follow these steps, stop running container docker stop test01 commit the … Read more
Basically, you have three options: Neither specify EXPOSE nor -p Only specify EXPOSE Specify EXPOSE and -p 1) If you specify neither EXPOSE nor -p, the service in the container will only be accessible from inside the container itself. 2) If you EXPOSE a port, the service in the container is not accessible from outside … Read more
The specific way to run it depends on whether you gave the image a tag/name or not. $ docker images REPOSITORY TAG ID CREATED SIZE ubuntu 12.04 8dbd9e392a96 4 months ago 131.5 MB (virtual 131.5 MB) With a name (let’s use Ubuntu): $ docker run -i -t ubuntu:12.04 /bin/bash Without a name, just using the … Read more
You may need to switch your docker repo to private before docker push. Thanks to the answer provided by Dean Wu and this comment by ses, before pushing, remember to log out, then log in from the command line to your docker hub account # you may need log out first `docker logout` ref. https://stackoverflow.com/a/53835882/248616 … Read more
As in the comments, there’s no default editor set – strange – the $EDITOR environment variable is empty. You can log in into a container with: docker exec -it <container> bash And run: apt-get update apt-get install vim Or use the following Dockerfile: FROM confluent/postgres-bw:0.1 RUN [“apt-get”, “update”] RUN [“apt-get”, “install”, “-y”, “vim”] Docker images … Read more
The best way to work around this is to specify the Dockerfile independently of the build context, using -f. For instance, this command will give the ADD command access to anything in your current directory. docker build -f docker-files/Dockerfile . Update: Docker now allows having the Dockerfile outside the build context (fixed in 18.03.0-ce). So … Read more
Remove the -it from your cli to make it non interactive and remove the TTY. If you don’t need either, e.g. running your command inside of a Jenkins or cron script, you should do this. Or you can change it to -i if you have input piped into the docker command that doesn’t come from … Read more
docker image tag server:latest myname/server:latest or docker image tag d583c3ac45fd myname/server:latest Tags are just human-readable aliases for the full image name (d583c3ac45fd…). So you can have as many of them associated with the same image as you like. If you don’t like the old name you can remove it after you’ve retagged it: docker rmi … Read more
