Can you run 2 Docker containers at the same time?
Answer is Yes. It is possible to run multiple docker containers using one docker file. 1. In using docker-compose is a tool that allows you to define and run multiple containers with a YAML file called `docker-compose.You need to use user-defined networks for connecting and communicating between containers. To create a user-defined network and add the containers to it, you can use the docker network create command to create the network, and the docker network connect command to connect a container to the network.It's ok to have multiple processes, but to get the most benefit out of Docker, avoid one container being responsible for multiple aspects of your overall application. You can connect multiple containers using user-defined networks and shared volumes.

Can multiple containers run on same port : well, it makes sense that both containers have their own interfaces, so yes they can establish their own set of ports and have no means to coordinate how ports are allocated amongst themselves as a group. So there is nothing to stop them from both running services on the same port.

How many docker containers can I run

Generally most folks run at most 10–20 containers per server and honestly if you run more than 50 you likely are doing something wrong. Kubernetes has a default limit of 110 pods per node, but you can increase this to 256. If course a pod can have multiple containers in the pod.

Is there a limit for docker container : By default, each container's access to the host machine's CPU cycles is unlimited. You can set various constraints to limit a given container's access to the host machine's CPU cycles. Most users use and configure the default CFS scheduler. You can also configure the real-time scheduler.

Now that you have prepared the containers and leveled the ground, it's time to secure the containers together. You can do this by using welding or bolting techniques. Welding provides a strong and permanent connection, but it requires the help of a professional welder. Bolting is a more DIY-friendly option.

How do I run all Docker containers

Step 4: Run your container

  1. In Docker Desktop, go to the Images tab.
  2. Next to your image, select Run.
  3. Expand the Optional settings.
  4. In Host port, specify 8089 .
  5. Select Run.

Since you have two applications and want to run them as two different containers inside a single Pod and you want minimum changes in your application API URL, then simply create create two different Services having your trageted ports. Thus you need 0 changes in your application's APP url.Generally most folks run at most 10–20 containers per server and honestly if you run more than 50 you likely are doing something wrong. Kubernetes has a default limit of 110 pods per node, but you can increase this to 256. If course a pod can have multiple containers in the pod.

A multi-container pod is a pod in Kubernetes that can run multiple containers together as a single unit. These containers share the same network namespace, storage volumes, and can communicate with each other.

How many containers can run on a host : Generally most folks run at most 10–20 containers per server and honestly if you run more than 50 you likely are doing something wrong. Kubernetes has a default limit of 110 pods per node, but you can increase this to 256. If course a pod can have multiple containers in the pod.

How many Docker containers can I run on an EC2 instance : Unlike a heavier virtual machine, you can run many small docker containers on a single machine. It is common to fill an EC2 instance with 10-20 small Docker containers.

How much RAM does Docker consume

Each Docker container you run consumes a tiny bit of system resources. If you go wild, running hundreds of containers without much RAM, your system is gonna choke. As a thumb rule, Docker itself recommends 2GB. But if your apps are the heavyweight champs, you might need way more.

Remember that containers, by default, run in isolation and don't know anything about other processes or containers on the same machine. So, how do you allow one container to talk to another The answer is networking. If you place the two containers on the same network, they can talk to each other.When running Docker containers with no special networking settings, multiple containers that use the same port can be run through port mapping. However, this opens up ports on the host machine which could be a security concern if several containers are running.

How do I start all containers at once : If you mean to create multiple containers at the same time then you will have to make use of docker-compose. This will startup any stopped containers.
