I would like to first create a Digital Ocean droplet(server) and then create multiple docker containers for various services inside that server.
I feel like this should be easy but I cannot find any examples of others doing this. Any help would be greatly appreciated.
You cannot really nest resources like that in Terraform. You have a two different ways to approach this, I would use the user_data argument that will run a script on your droplet that will issue the docker commands to pull down your container images and start your containers. Here is a blog post with an example.
Hope this helps.

This questions must have been asked many times before but i can't find any solution that can help me solve my problem.
I'm running VueJS application with Express/NodeJS as server and I know the best way is probably to separate them in 2 containers. But how can I make this work in 1 container with multi-stage or any other way.
Any tips would be appreciated! Thank you!
Run multiple services in a container
A container’s main running process is the ENTRYPOINT and/or CMD at the end of the Dockerfile. It is generally recommended that you separate areas of concern by using one service per container. That service may fork into multiple processes (for example, Apache web server starts multiple worker processes). 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.
If you need to run more than one service within a container, you can accomplish this in a few different ways.

I have the following application running on a Cloud VM. That is proving to be not economical.
As you can see this is a collection of different images. Is there a way to run this application on Azure serverless. I understand perhaps AKS(Kubernetes) might be one way to go. However, the YML config part might end up becoming too daunting for me. Kindly suggest if there are other approaches to this.
I have a three container group running on Azure, and an additional run once container which I'm aiming to run once a day to update data on a file mount (which the server containers look at). Additionally I'm looking to then restart the containers in the group once this had updated. Is there any easy way to achieve this with the Azure stack?
Tasks seems like the right kind of thing, however I seem to only be able to mount secrets rather than standard volumes, which makes it not able to do what's required. Is there another solution I'm missing?
Thanks!
Is anyone done Hyperledger fabric multi org in multi host using docker compose file.
I just need to know the feasibility, if possible please share the reference material as well.
I am also tried with the docker compose commands as mentioned in this link https://medium.com/#wahabjawed/hyperledger-fabric-on-multiple-hosts-a33b08ef24f
It is very well feasible and we have tried it out.
There are two ways you can achieve
1. Either docker-compose up with splitting the files or passing arguments as params where each org has to be brought up
2. Using stack deploy for a single file and keeping the constraints as per the schema 3.5 for docker compose file.
Rest all process remains the same.
You need to use docker swarm init to initialise the cluster and using the token generated add other VMs. Refer docker swarm guide for help.
I have node-applicatiot. It's running from terminal and do some operations. Operations include work with database "MongoDB".
I need to write dockerfile that create Docker-image from my app.
I read many information, but examples that I found tell about how to create web-app that running on some port. I need just run app from terminal.
What steps I must do?
unfortunately your question is rather vague and I am not really familiar with nodeJs, but as far as my understanding of Docker goes I will try and point you in some direction where you might find the information you are looking for or at least help you to ask a more specific question.
From what I can tell what you are looking for is probably a docker image that contains a nodeJs-Server. Then you would download that image and create a container from it, you would map the folder containing your node-application as a volume into the container, so the node-Server inside the container can deploy your application.
At our company we use a JBoss-Application Server inside a Docker-Container to deploy our Java-Applications in pretty much the way I described. Maybe you should look for some of the words I used on Google (docker volume, docker container, etc.), there are actually lots of documentation and tutorials on docker out there.
A good way to start would probably be here https://docs.docker.com/ ;)
