Setup Gitea on Raspberry Pi (3)

These instructions are based on this article: https://www.alexruf.net/2016/05/23/setup-gogs-git-service.html.

Setup Raspberry Pi with minimal Raspbian image. You need to connect to the HDMI port and set the following:

sudo raspi-config

There you need to enable the SSH server and you should change the hostname.

git remote add upstream https://github.com/some_user/some_repo
git fetch upstream
git checkout master
git reset --hard upstream/master  
git push origin master --force

Keep in mind, that this makes your repo look exactly like upstream - if you have commits, they will be eaten! If you want to update to upstream (but still keep your commits), you want git merge upstream/master. If you want to start a new patch based on upstream, the best way to do it is git checkout -b my-new-feature upstream/master

Of course, this all expects you have a remote named upstream, which you can create by doing git remote add upstream https://[upstream guy's repo url]
(Just to clarify, the term 'upstream' means the person you forked from)

Docker Reference

This week (May 2017) I have been learning about Docker... Here is what I've learned so far.

The shortcut commands in brackets refer to functions/aliases I've set up in my dotfiles.

Installing Docker on Ubuntu

sudo apt-get install docker docker-compose

#!/bin/bash

cd ~ 

# Install JDK

apt install openjdk-8-jre-headless


# Install & Start ES 0.90.1

gfabrizi

#!/bin/bash

# Save docker images
ds() {
  docker images | \
    cut -d ' ' -f 1 | \
    tail -n +2 | \
    xargs -t -n 1 -I {} -P 4 \
      sh -c 'docker save {} | bzip2 > $(echo "{}" | sed "s/^.*\///").tar.bz2'
}

    document.querySelector('body').appendChild(watchFrame);
};watchify();window.addEventListener('resize', watchify);
