Genesis Core Base Image

This is a base image for Genesis Core project. The image contains all necessary tools and libraries to be used in Genesis installations.

The key features are:

• Universal Agent service.
• Genesis root autoresize service. Tries to perform resize of the root partition at every boot if it's possible.
• Genesis bootstrap service. Runs the bootstrap scripts.

🛠️ Build

You need DevTools to build the image. Look the the install section for details.

Run the build command:

genesis build -i ~/.ssh/key.pub -f .

Where ~/.ssh/key.pub is your public key for the image.

Also you may set the GEN_USER_PASSWD environment variable to change the default user password.

export GEN_USER_PASSWD=secret
genesis build -i ~/.ssh/key.pub -f .

To build with local copy of the SDK, export the LOCAL_GENESIS_SDK_PATH environment variable:

export LOCAL_GENESIS_SDK_PATH=/path/to/gcl_sdk
genesis build -i ~/.ssh/key.pub -f .

🚀 Usage

Upload the image to your repository. Using API, CLI or web interface create a node with the image.

curl --location 'http://10.20.0.2:11010/v1/nodes/' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ****' \
--data '{
    
    "name": "vm",
    "project_id": "f1f14cf1-1639-40dc-b725-757506a202b4",
    "root_disk_size": 15,
    "cores": 1,
    "ram": 1024,
    
    "image": "http://10.20.0.1:8080/genesis-base.raw"
}'

📃 Bootstrap scripts

For next images in hierarchy you can add scripts that are executed at the very first boot of the node. Actually it can be any executable file and not only bash scripts. Put your scripts in the /var/lib/genesis/bootstrap/scripts directory and they will be executed in the order of the files in the directory.
