  2. Run git clone https://github.com/hackmdio/docker-hackmd.git.
  3. cd docker-hackmd && cd hackmd && docker build -t hackmdio/hackmd:0.4.4-1 . && cd ..
  4. sudo cp nginx.conf.example /etc/nginx/sites-enabled/hackmd && sudo service nginx reload
  5. sudo cp upstart.hackmd.conf /etc/init/hackmd.conf
  6. Run docker-compose up in your docker terminal.
  7. Wait until see th log HTTP Server listening at port 3000, it will take few minutes based on your internet.
  8. Press ctrl-C to stop
  9. Run sudo service hackmd start
  10. Open any browser and surf <machine IP>/hackmd/

Update

Start your docker and enter the terminal, follow below commands:

cd docker-hackmd ## enter the directory
git pull ## pull new commits
docker-compose pull ## pull new containers
docker-compose up ## turn on

Backup

Start your docker and enter the terminal, follow below commands:

  • run docker ps to check all your containers
~  docker ps
CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                    NAMES

  • backup postgresql by docker exec <postgresql_container_id> pg_dump hackmd -U postgres > <postgresql_backup_name>
~  docker exec 4949b888c1cb pg_dump hackmd -U postgres > postgresql_backup.sql
  • copy your backup out of container by docker cp <container_id>:<backup_path> <host_path>

Restore

Similar to backup steps, but last command is

~  cat postgresql_backup.sql | docker exec -i <container_id> psql -U hackmd

Custom build

The default setting would use pre-build docker image, follow below steps to customize your HackMD.

  1. Modify docker-compose.yml at line 8 image: hackmdio/hackmd:0.4.4 to build: hackmd.
  2. Change the config file in hackmd/config.json, example here.
  3. Run docker-compose build --no-cache in the docker terminal to build your own image.
  4. Then docker-compose up to startup.

Happy HackMD 😄
