# productive Docker host?
1. https://coreos.com/os/docs/latest/booting-on-ec2.html and select HVM AMI
2. create single node (open TCP and UDP all)
3. ssh into node
4. install Rancher, see below



###

# ubuntu ...
sudo apt-get -y install docker.io;

# ...or rhel...
sudo yum -y install docker docker-registry;
sudo systemctl start docker.service;

# ...or Fedora
sudo yum install docker-engine;
sudo systemctl start docker.service;

sudo docker pull ubuntu; 
sudo docker pull centos; 
sudo docker pull node;
sudo docker pull wordpress;

# Rancher Admin
docker run -d --restart=always -p 8080:8080 rancher/server
* first set local admin password
* second setup 'host' as the same address, add 'custom' host and paste command in via ssh

# Shipyard: Docker Webmin
# first: sudo bash, then:
curl -sSL https://shipyard-project.com/deploy | PORT=12121  bash -s; # Install
curl -sSL https://shipyard-project.com/deploy | ACTION=remove  bash -s; # Remove
# Shipyard available at http://localhost:12121
# Username: admin Password: shipyard

# DockerUI
docker run -d -p 9000:9000 --privileged -v /var/run/docker.sock:/var/run/docker.sock uifd/ui-for-docker


# Simple Docker UI: Chrome Docker Admin
https://chrome.google.com/webstore/detail/simple-docker-ui/jfaelnolkgonnjdlkfokjadedkacbnib/related?hl=en
* can be used to pull images
* cannot be used to create new containers

# Dockery Light
https://chrome.google.com/webstore/detail/dockery-light/cefhojablgaokgccloekpocgmffgecmm?hl=en
* Chrome Extensions is not maintained

# Portainer

# makes it quicker to ssh into a container; to see container name use: docker ps
dssh () { sudo docker exec -i -t "$@" bash; }

# interesting images:
centurylink/panamax-api
tutum/lamp
linode/lamp
castawaylabs/lamp-docker
drupal
https://hub.docker.com/r/strongloop/

# commands
docker rm --force `docker ps -qa`; # remove ALL containers

# minimal node container
docker run -i -t -h test.example.com --name somenodecontainer -m 256M mhart/alpine-node /bin/sh; # create container from image `mhart/alpine-node`

# container-to-container networking
* within each container, cat /etc/hosts to see hostname & ipaddress
* use docker link within coreos ssh, to insert entries into containers' /etc/hosts for their neighbors


 # docker run -dit ubuntu; # create a long running container with a random name.
