Requirements

Before setting up ghostcloud, ensure your system meets the following prerequisites:

• Ignite CLI, version 0.27.2
• Go programming language, version 1.21 or higher

Get started

To jumpstart your ghostcloud blockchain development, run the following command:

ignite chain serve

The serve command performs a series of actions: it installs necessary dependencies, compiles your blockchain's source code, initializes the default configuration files, and finally, launches your blockchain in a local development environment.

Configure

To tailor your development blockchain, modify the settings in the config.yml file according to your requirements.

How to use

This section describes how to interact with your ghostcloud blockchain using the command-line interface (CLI).

Deploying a new instance

To create a new deployment on your blockchain, use the command format below:

ghostcloudd tx ghostcloud create [NAME] [PAYLOAD] --from [KEY] --gas auto --yes

where

• [NAME] is your chosen name for the deployment.
• [PAYLOAD] is the path to either a directory or a zip file containing your deployment's content.
• [KEY] is the name of the key used for signing the transaction.

Optional flags:

• --description "[DESCRIPTION]" - A brief description of the deployment (optional).
• --domain [DOMAIN] - The domain that will be associated with this deployment (optional).

Important considerations:

• The [PAYLOAD] must have an index.html file located at the root.
• The size of the [PAYLOAD] is limited to a maximum of 5MB.

Example usage:

ghostcloudd tx ghostcloud create foobar ~/foobar.zip --from alice --gas auto --yes

In the example above, a new deployment named foobar is created using the contents of ~/foobar.zip, signed with the key alice. The transaction is set to calculate the gas automatically and is confirmed without further prompts.

Update an existing deployment

ghostcloudd tx ghostcloud update [NAME] [DESCRIPTION] [DOMAIN] [flags] --from [KEY] --gas auto --yes

where

• [NAME] is the name of the deployment to update.
• [DESCRIPTION] is the new description for the deployment.
• [DOMAIN] is the new domain associated with the deployment.
• [KEY] is the name of the key to use for signing the transaction.

Available flags:

• --website-payload [PATH] - (Optional) Provide the path to the new website payload, which can be a directory or a zip file.

Important considerations:

• If using --website-payload, ensure that the payload contains an index.html file at its root and that the total size does not exceed 5MB.
• [NAME], [DESCRIPTION], and [DOMAIN] must be provided together. If you do not wish to update a particular field, use the existing value.

Example usage:

ghostcloudd tx ghostcloud update myapp "Updated version" "newexample.com" --website-payload ~/newapp.zip \
  --from alice --gas auto --yes 

In this example, the myapp deployment is updated with new contents from ~/newapp.zip, a new description, and a new domain, all signed with the key alice. The --gas auto flag allows the transaction to automatically calculate the gas needed, and --yes confirms the transaction without additional prompts.

Remove an existing deployment

ghostcloudd tx ghostcloud remove [NAME] --from [KEY] --gas auto --yes

where

• [NAME] is the name of the deployment to remove.
• [KEY] is the name of the key to use for signing the transaction.

Example usage:

ghostcloudd tx ghostcloud remove myapp --from alice --gas auto --yes

In this example, the myapp deployment is removed from the blockchain, signed with the key alice. The --gas auto flag allows the transaction to automatically calculate the gas needed, and --yes confirms the transaction without additional prompts.

List all deployments

ghostcloudd q ghostcloud list

Available flags:

• --filter-by string - Apply a filter to the list of deployments. The filter can be creator.
• --filter-value string - The value to use for the filter.
• --filter-operator string - The operator to use for the filter. The operator can be equal.

Example usage:

ghostcloudd q ghostcloud list --filter-by creator \
  --filter-value gc13q9lpjm0zwse4msn5l6anwzznphxgnzxssf86x \
  --filter-operator equal

In this example, the command will return the list of deployments created by the address gc13q9lpjm0zwse4msn5l6anwzznphxgnzxssf86x.
