[5 Mins Docker Series] Minimalist Web Notepad – A Simple Online Notepad

主机优惠 • • 好物分享

This post introduces a small open source project from Github pereorga/minimalist-web-notepad,

It creates a online web notepad for you to store your text and at the same time you can share or collaborate it with others over the Internet. 

Introduction

This product is similar as your notepad in your Windows, but it is online which you also can share or collaborate the work with others. 
Demo Site:
It provides docker installation file to let you create your own image and spin up your own docker in your VPS. 

System Commands

In this lab, I am using Ubuntu 20.04 VM from Oracle Cloud Free Tier as an example. All following commands are based on this Ubuntu 20.04 version in Oracle Cloud platform. Please adjust it accordingly if you are using different system or platform. 
For more details about docker, Portainer, NPM configuration, please check following posts:
Commands list after run "sudo -i":

1 System update & upgrade:

apt update -y && apt upgrade -y

2 Increase SWAP size to at least 1024MB if your VPS ram is only 1GB

wget https://raw.githubusercontent.com/51sec/swap/main/swap.sh && bash swap.sh

3 Install Docker and Docker-Compose:

apt install docker.io -y 
apt install docker-compose -y

4 Install Portainer (Optional):

docker volume create portainer_data

docker run -d -p 9000:9000 --name portainer --restart always -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer-ce:latest

5 Install NPM (Nginx Proxy Manager) (Optional)

docker run -d -p 80:80 -p 81:81 -p 443:443 --name npm --restart unless-stopped -v ./letsencrypt:/etc/letsencrypt -v ./data:/data jc21/nginx-proxy-manager:latest

6 Install htop program (Optional)


apt install htop -y

7 Enable BBR on Ubuntu 20.04 (Optional)


Open the following configuration file vi /etc/sysctl.conf to enable enable TCP BBR.

vi /etc/sysctl.conf

At the end of the config file, add the following lines.

net.core.default_qdisc=fq
net.ipv4.tcp_congestion_control=bbr

Save the file, and refresh your configuration by using this command,

sysctl -p

Output:

root@vps:~# sysctl -p
net.core.default_qdisc = fq
net.ipv4.tcp_congestion_control = bbr

Now, Verify if BBR is enabled in your system,

sysctl net.ipv4.tcp_congestion_control

Output:

root@vps:~# sysctl net.ipv4.tcp_congestion_control
net.ipv4.tcp_congestion_control = bbr

Done!


8 Enable IPv6 and Limit Log File Size (Optional)


Add customized self defined IPv6 address segment to enable container's IPv6 fucntion. And limit log file's size and numbers in case log file to fill all hard drive's space. 
cat > /etc/docker/daemon.json << EOF
{
 "log-driver": "json-file",
 "log-opts": {
 "max-size": "20m",
 "max-file": "3"
 },
 "ipv6": true,
 "fixed-cidr-v6": "fd00:dead:beef:c0::/80",
 "experimental":true,
 "ip6tables":true
}
EOF

Restart Docker service:

systemctl restart docker

Steps to Install Minimalist Docker

Here I am using Play with Docker website as an example to demonstrate all steps. 

1 Create minimalist data folder which will store all data generated by your apps

$ mkdir -p /root/data/docker_data/minimalist

2 Download program code

Change your folder to the one just created, then use wget command to download zipped docker file.

$ cd /root/data/docker_data/minimalist

3 Unzip the docker.zip file and build the docker image
