How do I deploy a container to a remote Docker machine with ServerCat

Find out how ServerCat makes it simple to deploy a container to a number of Docker hosts with batch execution.

ServerCat is one in all my favourite instruments for remotely accessing and monitoring Linux servers. With a superbly designed UI and user-friendly construction, anybody can use this software to entry distant Linux servers.

But ServerCat has a number of different tips up its artful sleeve. One such trick is the power to batch-execute Docker deployments to any supporting server you’ve gotten related. With a single command, you’ll be able to deploy containers to all your Docker servers after which monitor them to verify they’re operating as anticipated. I’ll present you ways easy it’s to just do that by batch-deploying an NGINX container to a number of servers internet hosting Docker containers.

What you’ll have to deploy a container with ServerCat

You’ll want ServerCat put in on a macOS device, and at the least one Linux host related that runs Docker.

How do I deploy a container with ServerCat

Before we get into this, know that deploying a container with ServerCat isn’t completely a point-and-click affair, as a result of you will want to understand how to deploy that container by way of the command line. I’ll show an NGINX container deployment, which is comparatively easy.

The very first thing to do is open ServerCat in your macOS device. From the primary window, you must see the Execute entry within the left navigation (Figure A).

Figure A

In the Execute display screen (Figure B), you’ll see a listing of all of the accessible hosts on the high, the execute command area, and the Execute button.

Figure B

This isn’t solely used for deploying containers; you possibly can additionally, say, run sudo apt-get improve -y on any Ubuntu-based server. But for this demonstration, we’ll deploy a container.

At the highest, choose the entire Docker servers to which you wish to deploy the container. Next, within the Execute Command area, sort:

docker run --name docker-nginx -p 8080:80 -d nginx

With every thing set (Figure C), click on Execute to deploy the container to the chosen hosts.

Figure C

As you’ll be able to see in Figure D, one deployment succeeded, whereas the opposite didn’t.

Figure D

If I am going to Hosts after which double click on the Docker Swarm entry, I can run docker ps -a to find port 8080 is already taken, which prompted the error (Figure E).

Figure E

Then, I can try one other deployment using a special exterior port with the command:

docker run --name docker-nginx2 -p 8081:80 -d nginx

We need to rename docker-nginx to docker-nginx2 as a result of the primary title is already taken. That command will succeed, and our NGINX container shall be deployed to our Docker Swarm host.

Simple Docker deployment

Although ServerCat container deployment isn’t a full-on point-and-click affair, it does make it simple to spin up containers on a number of distant Docker nodes after which monitor these containers. If the fundamentals of Docker CLI deployment, ServerCat will assist make the deployment and monitoring of these containers a bit simpler. Give this all-in-one software a attempt, and see if it doesn’t change into your go-to technique of batch-executing containers to your Docker servers.
