Strategy for Distributing my solution

First of all, I am super new to Docker or container World in general.

So far, I built 2 images (both local and cannot push to hub being internal work)

I created a docker-compose file to be able to run the images in their own containers.

This all works great as expected. Now, the question comes up is how do i deliver it to the consumers so that they can just get it up and running in no time.

The another possible challenge that comes to my mind is: how do i deliver continuous updates to the images so that consumers get it hassle free.

I’d suggest using swarm mode, even with a single node it’d work great.

To deploy it in the first place all you need is Docker >=1.13.0 (I’d recommend the latest):

$ docker stack deploy -c docker-compose.yml vikceostack

To update the image, you could either give them a new Compose file and have them:

$ docker stack deploy -c docker-compose-new.yml vikceostack

or you might be able to update the service image manually as well:

$ docker service update vikceostack_service --image vikceo/image:newtag

if i m updating the image then why does it require a new docker-compose file? that wont change. something in the actual would chage. like for my case my web image also packs the web application. And i may need to just update the application code for some bug fixes or continues enhancements. Sorry may be i am missing something

Because you’d have to change something like image: vikceo/myapp:0.0.1 to image: vikceo/myapp:0.0.2 and apply the change.

so i see a problem here: which I raised in the my original question as well.

i do not have those repositories setup and can not use docker public registry as well. So, basically, my image is local.

I believe in my case when consumer sets up this then they would need to download
2 images files, 1 docker-composer.yml and need to setup docker and do docker stack deploy


  1. does this sounds right or totally weird to not have repository ?
  2. how to handle future updates in this scenario

You could have a private image that they have access to on Docker Hub, or docker save + docker load the images on your clients’ computers.

A little weird, since you need to get images around somehow, and that somehow is usually via registry.

I don’t understand.

so u r saying i can have a docker repositry which is accessible to me + some users i want ? I thought a docker repository is either purely private to owner or public

Yeah definitely, you can use Docker Hub “groups” concept to authorize only a specific subset of users to have access to a repository. So your users could make Docker Hub accounts (would not cost them anything if you pay for the private repo) and you could add them to this group.

does the update to really work require a different docker-compe file as u mentioned a new name? In other words is it smart if i just change the version number in the docker-compose.yml keeping its name same?

Yes, you can make modifications to an existing file and apply them using docker stack deploy. You do not have to have a brand new file with a different name.

is there a doc etc that explain how this stack deploy works in terms of what happens behind the scene

If you really want to know, read the source code :wink:

But playing with docker stack and docker service ( should give you quite a feel for it.
