Linking Docker Containers

29 March 2016 Docker

In previous tutorials I have built standalone containers i.e. everything in one “box”, webserver, application and database. One can see how building several containers like this for multiple applications will involve a lot of uneccessary duplication, storage, and processing. Docker is an ideal tool split these services into separate blocks and allow them to interact with each other seamlessly.

Making Docker Containers Web Accessible

11 March 2016 Docker

In previous tutorials we have accessed the docker applications by binding the containers exposed port 80 to a host port. If there is already a web application/s running on the host using port 80 then the containers port needs to bound to a redundant host port say 81 or upwards. Whilst this works in practice it is not very elegant.
