containers

问题 this is just a question about theory, my app is running perfectly... So, I have 3 services runing with docker-compose: a postgres database , a backend springboot and a frontend angular . From what I know, docker containers can acess ports from other docker containers without the need to expose the port, so there is no need to expose nor bind the ports because they are all containers and can access each other with the default bridge network mode (that's what I learned, don't know if this is

问题 Once you've created a task definition in Amazon's EC2 Container Service, how do you delete or remove it? 回答1: It's a known issue.

问题 I've got a docker-compose.yml : master: build: . slave: image: master hostname: slave command: run_slave How can I make docker-compose scale slave=5 generate machines with unique hostnames? ...e.g. something like this: slave1 slave2 slave3 slave4 slave5 回答1: There is no way to set the hostname to that value. If you need a unique identifier, I would use the unique container id, which you can get by running $(hostname) . 回答2: The accepted answer is correct, there is no way to set this using one

问题 I installed podman on RHEL 7.6 and can run normal docker command with sudo sudo podman run hello-world Is there a way to run it without sudo, without using usernamespace (similar to adding your user to the docker group when using regular docker command)?

But I am not able to enable/ setup suid on the machine (LDAP etc.) Currently, when run as a non-root user, I get this user namespaces are not enabled in /proc/sys/user
