# the primary reason we have two build stages is so SSH key of private repo's will never
# be in final image

# COPY IN BUILD SSH KEY
# It won't be copied to final image
# add this build arg to compose file

# first install pygmentize to the mac OS X or macOS system with the built-in python
sudo easy_install Pygments

# then add alias to your ~/.bash_profile or ~/.bashrc or ~/.zshrc etc.

# so docker cloud now has swarms fleet mgmt
# and you can use something like this to connect from cli to your swarm via docker remote api:
docker run --rm -ti -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_HOST dockercloud/client bretfisher/swarm1

# but maybe we can put that in a bash alias to make it easier
alias cswarm="docker run --rm -ti -v /var/run/docker.sock:/var/run/docker.sock -e DOCKER_HOST dockercloud/client"

#then
cswarm bretfisher/dude-swarm1

1. download these two files to the same directory
2. docker-compose up
3. http://localhost should show you "it works" which is apache being reverse-proxied through nginx
4. docker sets up DNS for web based on compose service name so the nginx front-end can find http://web
5. proxy is set to listen on public port 80 on host so it'll receive incoming traffic, then push to httpd

warning: /proc/config.gz does not exist, searching other paths for kernel config ...
info: reading kernel config from /boot/config-4.4.0-64-generic ...

Generally Necessary:
- cgroup hierarchy: properly mounted [/sys/fs/cgroup]
- apparmor: enabled, but apparmor_parser missing
    (use "apt-get install apparmor" to fix this)
- CONFIG_NAMESPACES: enabled
- CONFIG_NET_NS: enabled

2021 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Docker VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

# problem: when presenting, I want to obscure
# my prompt to act like it's at root of file system 
# and be very basic with no git info, etc.

# solution: this theme lets you set a ENV to the path 
# of your presentation, which will help remove unneeded prompt
# features while in that path 

# oh-my-zsh theme for presenting demos
# based off the default rubbyrussell theme
