How to push the application to aws and run with docker

Hi Experts,

   I got a server which runs applications with docker and aws, running from console(putty).  The command to run is as follows:-

docker run --name ts_pull ${ts_environment[@]}  -d  --restart always start pull

Open in new window

I can understand is from aws.  Can any tell me how this container application is pushed to aws?

From the documentation I found Dockerfile is available, from which the docker image is built.  I don't understand how to push this to aws and run with the docker.

Please throw some light over it.

with many thanks,

Bharath AK

Sounds like you're using a stock AWS instance, rather than custom.

If you build a custom AWS instance, then you bake in all your Docker code into the instance.

If you use a stock AWS instance, then you root ssh into your AWS instance, using the ssh key AWS returns when instance spins up.

Then always add another ssh key so you always have a known key to access all your instances, so you can throw away the temp key returned from AWS at instance spin up time.

Then pull files you require onto your AWS instance, normally via curl or wget.

Then build your Docker container + spin it up.

Hi David,

      Thanks for your reply.   Aws instance is ubuntu machine.  I connect to it through putty.  I don't understand  what stock aws instance means.  everything is in the ubuntu machine.   it has postgres database, elastic search, python, wagtail, django, dockers etc.   Harvest-ts is a python application, which is run as cron.  I don't understand how this is pushed into aws as docker container.  Could you please elaborate more or provide me links so that I can learn and understand what you mean.  

With Many thanks,

Two types of instances.

Custom - you generated it from scratch + you'd know if you did this.

Stock - you use an already existing AWS instance.

If you connect through Putty then you're likely running a root shell.

So you'll just follow one of the many guides to running a Docker container on Ubuntu.

Just think of your AWS instance as a dedicated server running Ubuntu... which it is, although very slow as AWS uses have VMs.

Just go to the Docker site + or where ever you acquired the Docker container config you're using for your application. is a good starting point.

Hi David,

      Thanks for your reply.

      a) There is a DockerFile in repository to build the image for harvest-ts.  My understanding is  After building the docker image it is pushed to aws?  and docker run pulls the image from aws and runs the container.  This is what i have understood. is this right?  please correct me if i am wrong.  my next question is how to push this image to aws.

    b)  I have another question, harvest -ts is a cron it stops and continues after some time.  if this as docker container, will it stop and start at intervals.

     Please correct me wherever I am wrong.  sorry, I feel I am troubling with more questions I don't have clarity

Thank you so much.

Kind Regards,

Hi Bharath,
docker run --name ts_pull ${ts_environment[@]}  -d  --restart always start pull

From the above command, the docker image is pulled from AWS ECR ( Ec2 Container registry) not docker hub. is the AWS ECR account
harvest-ts  is the image name
1.0.2 is the tag assigned to it. We can have multiple tags for the same image.

Now coming to your question "How docker image is pushed?"
      As you are using custom docker image, there will be dockerfile which contain all the configuration required for it. Once the image created using the following command
      docker built -t imagename:tagname .

After executing the above command new Docker image gets generated. Now the next step is to push docker image to Docker registry.  I hope you are using AWS ECR.
So first you need to log in your registry account using the following command,

Make sure that you have installed AWS CLI.

aws ecr get-login --no-include-email --region us-west-2

Where us-west-2 is the region where you created the registry.

Once you logged, tag the newly created image to push AWS registry,

using the following command,
docker tag imagename:tag

Now you can push the image directly to AWS ECR using the following command,

docker push

I Hope the above information helps you. Let me if you have any clarifications,
