Docker を利用した Web アプリケーションのデプロイ - クックパッド開発者ブログ
技術部の鈴木 (id:eagletmt) です。 クックパッドでは一部の Web アプリケーションサーバで Docker が使われており、今回はそのデプロイ方法について紹介します。 Docker で Web アプリケーションをデプロイするときには、まだまだベストプラクティスがある状況ではありません。 たとえば、どのように無停止でデプロイするか、どのようにコンテナと通信するかといった問題があります。 最初に Apache Mesos と Marathon などのツールを検証しましたが、クックパッドの環境において使いやすそうなものはなく、最終的に自前でデプロイのしくみを作ることにしました。 しかし Docker 周辺のツールは様々な新しいものが出てきている最中です。 今はまだベストなものが無いけれども、近いうちによりよいものが出てくるかもしれません。 そのため、できるだけ単純なしくみにしておく
A Rails Development Environment with Docker and Vagrant
A Rails Development Environment with Docker and Vagrant Onboarding new developers to a Rails projects is still a far harder task than it should be. A big part of this is that setting up a development environment for an app or suite of apps, getting the correct ruby versions, database versions etc running locally, can in many cases take upwards of a day. A combination of Vagrant and Docker can make
Why can't I use Docker CMD multiple times to run multiple services?
I have built a base image from Dockerfile named centos+ssh. In centos+ssh's Dockerfile, I use CMD to run ssh service. Then I want to build a image run other service named rabbitmq,the Dockerfile: FROM centos+ssh EXPOSE 22 EXPOSE 4149 CMD /opt/mq/sbin/rabbitmq-server start To start rabbitmq container，run： docker run -d -p 222:22 -p 4149:4149 rabbitmq but ssh service doesn't work, it sense rabbitmq'
Docker Registry or How to Run your own Private Docker Image Repository
Docker allows to bundle artifacts and configurations in an image. These images run as light weight system-level virtual machines. In my previous articles, I showed how to use Docker in general and how to use networking . In this article, I will show you how to manage images in a private Docker registry — basically a git repository for images — and run a production grade registry. As in my previou
A Rails Development Environment using Docker through Fig. | Whitesmith
Warning: This post is written by the DevOps guy, not the Rails guy. This post, however, is to be read by you, Rails girls and boys. It assumes the reader is not familiar with Docker. For those of you who already know Docker, I’m sure you’ll enjoy Fig. If you’re in a hurry, jump straight to the TL;DR. Introduction Onboarding a member to a project is usually a painful process, especially when it has
Run a service automatically in a docker container
I'm setting up a simple image: one that holds Riak (a NoSQL database). The image starts the Riak service with riak start as a CMD. Now, if I run it as a daemon with docker run -d quintenk/riak-dev, it does start the Riak process (I can see that in the logs). However, it closes automatically after a few seconds. If I run it using docker run -i -t quintenk/riak-dev /bin/bash the riak process is not

How to enter in a Docker container already running with a new TTY
I have a container that is running the Apache service in the foreground. I would like to be able to access the container from another shell in order to "poke around" inside it and examine the files. At the moment, if I attach to the container, I am left looking at the Apache daemon and cannot run any commands. Is it possible to attach another tty to a running container? Possibly, I can take advant
