Here we will need only a single host, so you can skip the etcd discovery part and the change of the num_instances variable. Using Vagrant, I have created this blog that shows how this can be done in less than 10 Minutes, if Vagrant and Virtualbox is installed.

Manual Build from Dockerfile Prerequisites when comparing docker with other container technologies, we find that docker is by far the most popular container technology as of today.

when comparing the performance of Rails on Windows and dockerized Rails on Windows, we experience a 50% performance gain.

A layered container design helps to further reduce latencies and download volumes since unchanged layers can be cached. compared to Hypervisor-based virtualization technologies, the resulting images are much more lightweight and thus are much easier to handle and share.similar to Hypervisor based virtualization technologies, container technologies help to create portable application images by bundling libraries with the application and by providing an environment that is independent from other applications.Here are the reasons, why I have chosen to containerize my web application using Docker: Next Steps towards Continuous Integration.If you are interested in a more lightweight „Hello World“ example with (probably) <15 MB of downloads during the process, you might be interested in this example. Note: the procedure requires Internet downloads of >1 GB.

Next possible steps towards full CI/CD (continuous integration/continuous deployment) are discussed a the end of the blog.

This will allow us to automatically create a new Docker image in the background, each time a code change is pushed to the Software repository.

In a second step, we will create a Link (via a „Webhook“) between the Github Software repository and the Docker Hub docker image repository.

which base image to use, which files to copy, which commands to perform and which ports to expose.

we will create and test a so-called Dockerfile that describes all automation steps: e.g.

This blog is exploring a tiny aspect of this automation framework: the containerization of an application and the automatic creation of a Docker image from source code for a Rails Web application as target application. For that, Continuous Integration (CI) and continuous deployment (CD) are made easy.

The my-first-redis container is going to be referred to as redis within the second container.What, if you could release and deploy fully tested and bullet-proof software on a day by day basis? Isn’t this a huge effort for hobby developers like me? Even for hobby developers, Docker and its ecosystem promises an easy way to automate the integration and deployment of the software. The command initiated a new Redis container ( my-second-redis), based on the initial redis image. Use the -link option to create and connect a new container to the existing Redis instance: sudo docker run -it -rm -name my-second-redis -link my-first-redis:redis -d redis Access Redis from Another Docker Containerġ. Change the path to match the location on your system. The location of the nf file in this example is myfirstredis/nf. If you have created a custom Redis configuration file, use the following command to load the file at container launch: sudo docker run -name my-first-redis -v /myfirstredis/nf:/usr/local/etc/redis/nf -d redis The nf file allows you to set up authentication, limit commands, and define other security-oriented settings. Type exit to close the connection with the Docker container. Once you have explored redis-cli commands, type quit to return to the container terminal interface.ĥ. A list of data types and commands is available in our comprehensive guide Redis Data Types With Commands.Ĥ. The result retrieves the previously defined pnap value. You can retrieve the value using the unique key name and the get command: get name
