How to create the Joplin server with the docker?

1. Get the docker sample configuration file. 

$wget https://raw.githubusercontent.com/laurent22/joplin/dev/.env-sample
$move .env-sample .env
$vim .env

2. The example configuration will like below: 

#=============================================================================
# PRODUCTION CONFIG EXAMPLE
# -----------------------------------------------------------------------------
# By default it will use SQLite, but that's mostly to test and evaluate the
# server. So you'll want to specify db connection settings to use Postgres.
#=============================================================================
#
# APP_BASE_URL=https://example.com/joplin
# APP_PORT=22300
# 
# DB_CLIENT=pg
# POSTGRES_PASSWORD=joplin
# POSTGRES_DATABASE=joplin
# POSTGRES_USER=joplin
# POSTGRES_PORT=5432
# POSTGRES_HOST=localhost
#============================================================================= 
# DEV CONFIG EXAMPLE
# -----------------------------------------------------------------------------
# Example of local config, for development. In dev mode, you would usually use
# SQLite so database settings are not needed.
#=============================================================================
#
# APP_BASE_URL=http://localhost:22300
# APP_PORT=22300

3. If normal usage, use PRODUCTION section. 

PS:If only for debug or demo, use DEV section. 

APP_BASE_URL=https://example.com/joplin 
APP_PORT=22300
DB_CLIENT=pg
POSTGRES_PASSWORD=joplin
POSTGRES_DATABASE=joplin
POSTGRES_USER=joplin
POSTGRES_PORT=5432
POSTGRES_HOST=localhost

PS. Please change the POSTGRES_PASSWORD with you want. 

4. But, even use the docker, this docker will connect to your localhost DB. So, you must manually create the DB on your localhost. 

$sudo -u postgres psql

When you entry into the PostgreSQL console, please type the below command: 

PS. The PASSWORD must equal the POSTGRES_PASSWORD. 

CREATE DATABASE joplin;
CREATE USER joplin WITH PASSWORD 'yourpassword';
ALTER ROLE joplin SET client_encoding TO 'utf8';
ALTER ROLE joplin SET default_transaction_isolation TO 'read committed';
ALTER ROLE joplin SET timezone TO 'UTC';
GRANT ALL PRIVILEGES ON DATABASE joplin TO joplin;
\q

5. Run the docker.

$docker run --net=host --add-host=host.docker.internal:127.0.0.1 --env-file .env -p 22300:22300 joplin/server:latest

6. You can visit the local host on browser. 

http://localhost:22300/ 

7. The default login setting: 

Default username: admin@localhost 

Default password: admin 

8. You can create the bash file to easily run the docker: 

#!/bin/bash
docker pull joplin/server:latest
docker stop joplin
docker rm joplin
docker run -d --restart unless-stopped --name joplin \
			  --net=host \
              --add-host=host.docker.internal:127.0.0.1 \
              --env-file .env \
              -p 22300:22300 \
              joplin/server:latest
