VSTS Docker Release step

Question

I'm confused as to what is required to push my project docker container onto my production server from docker repository using VSTS.

I have done the following steps:

1. Created my application with Dockerfile
2. ran the build on VSTS to create a docker container
3. Pushed that container into my hub.docker.io account.

I am manually able to log ontu my linux (ubuntu 16) box and pull the container down and run it 100%.

I would like to create a release step/action within VSTS to do that last manual step for me. Is this possible? If so can someone explain the steps or point to a good guide.

NB: The web box is my own private VPS box, no major cloud provider, just straight ubuntu with docker installed.

Answer 1

You have different option now. You can use a tool like Ansible to create a script and run on your remote server.

Or you can create a script on remote server which does the whole update process

/var/myapp/update.sh

#!/bin/bash
docker pull myimage:latest
docker stop myapp
docker rm myapp
docker run -d -p 80:80 --name myapp myimage:latest

Setup a key based SSH session and then use below

ssh -i keyfile <user>@<Server> bash -c "/var/myapp/update.sh"

Edit-1

For the tty issue change the ssh command to

ssh -t -i keyfile <user>@<Server> bash -c "/var/myapp/update.sh"

For the sudo issue you can add your user to docker group

sudo usermod -aG docker <user>
