docker pull できなくなったとき
docker pull できなくなったとき、その他yumとか通信できなくなったとき、ゴミnetworkがあるみたい。

localstack 動かしてみた
localstack
ローカルでAWS検証できるよーと教えていただきました。
SQSを検証したいのでやってみます。
git cloneしますっ
$ git clone https://github.com/atlassian/localstack.git
Cloning into 'localstack'...

↓を参考に起動します
dockerです
$ docker run -it -p 4567-4578:4567-4578 -p 8080:8080 atlassianlabs/localstack
docker: Cannot connect to the Docker daemon at tcp://192.168.59.103:2376. Is the docker daemon running?.
See 'docker run --help'.
エラーになりますねー。ググると以下の情報がありました。
環境変数を調べます
$ export -p
declare -x DOCKER_CERT_PATH="/Users/xxxxx/.boot2docker/certs/boot2docker-vm"
declare -x DOCKER_HOST="tcp://192.168.59.103:2376"
declare -x DOCKER_TLS_VERIFY="1"
先のサイトにあったように DOCKER_某 を削除しますー
$ unset DOCKER_CERT_PATH
$ unset DOCKER_HOST
$ unset DOCKER_TLS_VERIFY
再び・・・
$ docker run -it -p 4567-4578:4567-4578 -p 8080:8080 atlassianlabs/localstack

sudo つけてみた、、、

Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker client contacted the Docker daemon.
2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
3. The Docker daemon created a new container from that image which runs the
executable that produces the output you are currently reading.
4. The Docker daemon streamed that output to the Docker client, which sent it
to your terminal.
To try something more ambitious, you can run an Ubuntu container with:
$ docker run -it ubuntu bash

ブラウザで localhost みると、、、
オーケー！
プロセスみてみる、、、sudoつけてね
~ $ sudo docker ps

nginxが動いているね。
webserver を止めてみる、、、
~ $ sudo docker stop webserver
