By / 7 November 2017 In our journey migrating to Docker for local dev we found ourselves running into issues with 'discovery' of services eg. In our first iteration we used, allowing our services to talk to each other, some downsides to this were: • Tricky to compose an advanced relationship, lets use PHP and PanthomJS as an example: • PHP needs to know where PhantomJS is running • PhantomJS needs to know the domain of the site that you are running locally • Wouldn't it be great if we could just use 'localhost' for both of these configurations?
• DNS entries only available within the containers themselves, cannot run utilities outside of the containers eg. Ayu Mayu Alternative Download For Microsoft. Mysql admin tool With this in mind, we hatched an idea. What if we could just use 'localhost' for all interactions between all the containers. • If we wanted to access our local projects Apache, (inside and outside of container) • If we wanted to access our local projects Mailhog, (inside and outside of container) • If we wanted to access our local projects Solr, (inside and outside of container) All this can be achieved with Linux Network Namespaces in Docker Compose.

By default, the following happens when a container gets created in Docker: • Its own Network Namespace is created • A new network interface is added • Provided an IP on the default bridge network However, if a container is created and told to share the same Network Namespace with an existing container, they will both be able to interface with each other on 'localhost' or '127.0.0.1'. Here are working examples for both OSX and Linux.
