KAGOYA CLOUD/2でUbuntu 16.04インスタンスを作る場合の初期スクリプトっぽいなにか。途中いくつかの入力があるので手動で動かす必要あり。

install_kagoya_ubuntu16.04.sh

#! /bin/env bash

# update 18.04
apt update -y
apt upgrade -y
# reboot
do-release-upgrade

# package install
apt install -y zsh unzip ctags make gcc libssl-dev libreadline-dev zlib1g-dev libbz2-dev libsqlite3-dev libffi-dev

# install docker
apt install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
apt-key fingerprint 0EBFCD88
add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"
apt update
apt install -y docker-ce

# delete unused package
apt clean
dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d' | xargs sudo apt-get -y purge

# create users
groupname=user
username=momotaro
groupadd $groupname
useradd -m -g $groupname -G sudo -s $(which bash) $username
mkdir /home/$username/.ssh
chown $username:$groupname /home/$username/.ssh
chmod 700 /home/$username/.ssh
passwd $username  # => input password

# setting iptables with ufw
ufw default deny
ufw allow ssh
ufw enable
