I recently had the following problem:
We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like
ssh -L 3306:localhost:3306 remotehost

# CORS header support | |
# | |
# One way to use this is by placing it into a file called "cors_support" | |
# under your Nginx configuration directory and placing the following | |
# statement inside your **location** block(s): | |
# | |
# include cors_support; | |
# | |
# As of Nginx 1.7.5, add_header supports an "always" parameter which |
# delete local tag '12345' | |
git tag -d 12345 | |
# delete remote tag '12345' (eg, GitHub version too) | |
git push origin :refs/tags/12345 | |
# alternative approach | |
git push --delete origin tagName | |
git tag -d tagName |
// === Arrays | |
var [a, b] = [1, 2]; | |
console.log(a, b); | |
//=> 1 2 | |
// Use from functions, only select from pattern | |
var foo = () => [1, 2, 3]; |
/* ~/Library/KeyBindings/DefaultKeyBinding.Dict | |
This file remaps the key bindings of a single user on Mac OS X 10.5 to more | |
closely match default behavior on Windows systems. This makes the Command key | |
behave like Windows Control key. To use Control instead of Command, either swap | |
Control and Command in Apple->System Preferences->Keyboard->Modifier Keys... | |
or replace @ with ^ in this file. | |
Here is a rough cheatsheet for syntax. | |

const flatten = (n) => flattenTco(n, []); | |
console.log(flatten([[1,[2,[[3]]]],4,[5,[[[6]]]]])) |

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...
// see: https://github.com/chadoe/docker-cleanup-volumes
$ docker volume rm $(docker volume ls -qf dangling=true)
$ docker volume ls -qf dangling=true | xargs -r docker volume rm
See this issue.
Docker best practise to Control and configure Docker with systemd.
Create daemon.json
file in /etc/docker
:
{"hosts": ["tcp://0.0.0.0:2375", "unix:///var/run/docker.sock"]}
