nginx-ssh

Simple Ubuntu docker images with SSH access and nginx

Running zuolan/nginx-ssh

docker run -d -p 2222:22 -p 80:80 zuolan/nginx-ssh

The first time that you run your container, a random password will be generated for user root. To get the password, check the logs of the container by running:

docker logs <CONTAINER_ID>

You will see an output like the following:

	========================================================================
	You can now connect to this Ubuntu container via SSH using:

	    ssh -p <port> root@<host>
	and enter the root password 'U0iSGVUCr7W3' when prompted

	Please remember to change the above password as soon as possible!
	========================================================================

In this case, U0iSGVUCr7W3 is the password allocated to the root user.

Done!

Setting a specific password for the root account

If you want to use a preset password instead of a random generated one, you can set the environment variable ROOT_PASS to your specific password when running the container:

docker run -d -p 2222:22 -p 80:80 -e ROOT_PASS="mypass" zuolan/nginx-ssh

Adding SSH authorized keys

If you want to use your SSH key to login, you can use AUTHORIZED_KEYS environment variable. You can add more than one public key separating them by ,:

docker run -d -p 2222:22 -p 80:80 -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" zuolan/nginx-ssh

About Nginx

Start your image building the external ports 80 in all interfaces to your container:

docker run -d -p 80:80 zuolan/nginx-ssh

Test your deployment:

curl http:https://localhost/

Hello world!

Loading your custom application

In order to replace the "Hello World" application that comes bundled with this docker images, first create a new empty folder. Go to the new folder and create two subfolders: sites-enabled and app. Copy your configuration files to sites-enabled and you application files to app. Then create a new Dockerfile with the following contents:

FROM zuolan/nginx-ssh
ADD sites-enabled/ /etc/nginx/sites-enabled/
ADD app/ /app/
RUN chown -R www-data:www-data /app/
EXPOSE 80

Remember to put your configuration files under the folder named sites-enabled and your website files under the folder app. Also, if you want to use a different port, change the EXPOSE 80 in Dockerfile as well.(eg. EXPOSE 443 80 will allow connections go through port 443 and 80). After that, build the new Dockerfile:

docker build -t username/my-nginx-ssh

And test it:

docker run -d -P username/my-nginx-ssh

Test your deployment:

curl http:https://localhost/

That's it!
