Configuration

By default deploy(1) will look for ./deploy.conf, consisting of one or more environments, [stage], [production], etc, followed by directives.

[stage]
key /path/to/some.pem
user deployer
host n.n.n.n
port nn
repo git@github.com:test/test.git
path /var/www/myapp.com
ref origin/master
post-deploy /var/www/myapp.com/update.sh

Directives

key (optional)

Path to identity file used by ssh -i.

  key /path/to/some.pem

Deploy on a Docker container

This is a basic demo showing how to deploy a project from Git to a running Docker container.

Installation

$ git clone https://github.com/ionpantalon/docker_deployment.git

Create the docker container

Get the version of Docker

$ docker version

Let's start by creating a Docker image from the Dockerfile. If you are not familiar with Docker or never used it before have a look at Docker docs

$ docker build -t 'my-image-name' .

Test if the image was created using

$ docker images

Create a container using my-image-name

$ docker run -dt --name dep_test my-image-name

• -t,--tty Allocate a pseudo-TTY
• -d, --detach Run container in background and print container ID

To check if the container is running and to get information about it like the name, size,etc, 'docker ps' can be used

$ docker ps or docker ps -a

Use SSH to connect to Git

Check if SSH is installed

$ ssh -V

Check the .ssh dir

$  ls -a ~/.ssh 

To generate new keys

$ ssh-keygen 

To start the agent

$ ssh-agent /bin/bash

Next let's load the new generated keys on the ssh-agent

$ ssh-add ~/.ssh/id_rsa 

Check if it was succesfully loaded

$ ssh-add -l 

Next copy the content of .ssh/id_rsa.pub and paste into SSH Key field on your git account

To test it clone the project using

$ git clone git@bitbucket.org :< accountname>/<reponame>.git

deploy.sh

Edit the variables to the appropiate paths and settings to match your project configuration

To deploy you can run it manually using

$ sudo ./deploy.sh

Or you can configure a web hook to deploy on certain events. When one of those events is triggered, a HTTP POST payload to the webhook's configured URL is sent. For more information about how to set up a web hook check Git webhooks

Test

To test if the project was succesfully deployed login on the container and check the deployment path

$ docker exec -ti dep_test /bin/bash

• -t, --tty Allocate a pseudo-TTY
• -i, --interactive Keep STDIN open even if not attached
