🐢 mrs_docker-lazy

mrs_docker-lazy offers a smooth and efficient workflow for Docker users especially when managing multiple remote machines.

---

✨ Features

• 🚀 Simplified workflow
• 🌐 Scalable across multiple remote machines
• 🚫 Never SSH: you can work always on your local machine
• 📡 No Internet needed.

🐳 Requirements

Ensure the following are installed on your local machine:

• Docker

• LazyDocker

• Ansible

• Tmuxinator

• Copy both the private and public SSH keys from ./ssh to your SSH configuration folder (usually ~/.ssh).

🛠️ Installation & Setup

1. Clone the Repository

git clone [email protected]:manuelboldrer/mrs_docker-lazy.git ~/git/mrs_docker-lazy

2. Prepare the Remote Machine(s)

• Install Docker.
• Ensure the public SSH key is added to ~/.ssh/authorized_keys.
  You can use:

ssh-copy-id -i ~/.ssh/ansible [email protected]

• Enable remote access to Docker:

sudo systemctl edit docker.service

Add:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H fd:// -H tcp://0.0.0.0:2375 --containerd=/run/containerd/containerd.sock

Then:

sudo systemctl restart docker.service

Verify the service is active.

🚀 Usage

1. Create and Load Docker Images to Remote Machines

If do not want to DockerHub or a local registry, a nice alternative is to use Ansible:

• Edit inventory.ini to include remote IPs and usernames.
• Add your image folder to load_custom_config/shared_data/.
• Run:

./run_all.sh

⚙️ In build_image.sh, export_image.sh, and image_loader/load_docker_image.yml, be sure to set the correct image name. (it should be fixed)

2. Compile Workspace (arm64/amd64), Create and Load Docker Images to Remote Machines

Place your workspace inside:

catkin_workspace_uvdar/src

change inventory.ini and common_vars.sh properly and run ./run_all.sh

3. Start TMUX Session

• Configure tmux_session/session.yml.
• Run:

cd tmux_session
./start.sh

4. Run in Synchronous Mode

./up.sh && lazydocker

🐞 Note: Lazydocker can be buggy in "stack" mode (if you run it in the same directory as the Docker Compose file). Change directory if it misbehaves.
⚙️ You can run custom commands within Lazydocker (check the config in the lazydocker/ folder). For more check LazyDocker Docs
