¶Deploy with Docker & Docker Compose

Preparation steps
- Install Docker and Docker Compose
- Ensure you have Docker and Docker-compose (v2 is required) installed and operational. If you don't have them installed, you can conveniently set them up using Docker's official helper script:

$ curl -L https://get.docker.com | sh
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 21596  100 21596    0     0  95191      0 --:--:-- --:--:-- --:--:-- 95557

================================================================================

To run Docker as a non-privileged user, consider setting up the
Docker daemon in rootless mode for your user:

    dockerd-rootless-setuptool.sh install

Visit https://docs.docker.com/go/rootless/ to learn about rootless mode.


To run the Docker daemon as a fully privileged service, but granting non-root
users access, refer to https://docs.docker.com/go/daemon-access/

WARNING: Access to the remote API on a privileged Docker daemon is equivalent
         to root access on the host. Refer to the 'Docker daemon attack surface'
         documentation for details: https://docs.docker.com/go/attack-surface/

================================================================================

To run Docker commands without using sudo, add the current user to the Docker group. If you are unsure who the user is, check the current user by running:

$ whoami
alexlai
$ sudo usermod -aG docker $USER
$ id alexlai
uid=1026(alexlai) gid=1026(alexlai) groups=1026(alexlai),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),100(users),107(lpadmin),108(sambashare),989(docker)
$ sudo reboot now

¶Deploy Rocket.Chat on Docker

Fetch the compose file
- Go to your preferred directory and create a compose.yml file and copy the content from our example.
- Alternatively, you can use the curl command to download the example compose.yml file by executing this command:
- curl -L https://raw.githubusercontent.com/RocketChat/Docker.Official.Image/master/compose.yml -O

$ mkdir -p ~/build/Dcokerfile && cd $_
$ curl -L https://raw.githubusercontent.com/RocketChat/Docker.Official.Image/master/compose.yml -O
$ ls
compose.yml
