Help! I can’t connect to my EC2 instance! Woah! My box just stopped talking to me! Hey! I can’t access the server! These and other variations on the connectivity theme are some of the most common problems raised on the Amazon EC2 forum. The EC2 community and Amazon employees do a valiant job helping users track down and solve these issues despite the facts that (1) there are hundreds of reasons wh
のっぴきならぬ事情でDockerコンテナ内からホストへlocalhost でアクセスする必要なときに役立ちそうなのでメモ。 Dockerコンテナ内からホストへアクセスするには こちらの記事が参考になりました。 --add-host オプションを利用すればなんとかなりそうです。 Dockerのコンテナの中からホストOS上のプロセスと通信する方法 - Qiita https://qiita.com/Iju/items/badde64d530e6bade382 localhost じゃなくて良いのなら host.docker.internal というDNS名が用意されているので、それを利用すればよさそうです。 ドキュメントによるとMac/Windowsで利用できそうです。 Networking features in Docker Desktop for Windows | Docker Doc

Update (2018-03-22) Since I wrote this document back in 2014, Docker has developed the macvlan network driver. That gives you a supported mechanism for direct connectivity to a local layer 2 network. I’ve written an article about working with the macvlan driver. This article discusses four ways to make a Docker container appear on a local network. These are not suggested as practical solutions, bu
When the Internet was built, computers weren’t mobile. They sat in offices next to data centers. The Internet has changed but the assumptions made 30 years ago are making your experience slower and less secure. 1.1.1.1 with WARP replaces the connection between your device and the Internet with a modern, optimized, protocol.

Hey, I noticed that recently a bunch of people has been getting to the website through queries about HAProxy in the context of AWS - mainly how to receive traffic through a set of instances and forward them to another set of machines. As I aim at making this blog as much practical as I can, I feel that if I taught the basics around AWS networking first, then I could have the ground set for further
Vagrantfileを準備する VirtualBox上にテスト用のVM(host1)を作ろうと思うのですが、bridgeが使えるようにするにはネットワークアダプターの選択肢をデフォルトから変更する必要があります。 Vagrantfileは下記のようになります。 Vagrant.configure(2) do |config| config.vm.box = "ubuntu/trusty64" config.vm.hostname = "host1" config.vm.network "private_network", ip: "192.168.33.10" config.vm.provider "virtualbox" do |v| v.memory = "2048" # ネットワークアダプタに変更を加える v.customize ['modifyvm', :id, '--nicty
In our last post we covered what docker does with container networking in a default configuration. In this post, I’d like to start covering the remaining non-default network configuration modes. There are really 4 docker ‘provided’ network modes in which you can run containers… Bridge mode – This is the default, we saw how this worked in the last post with the containers being attached to the do
