Requirements

Install the following before running the playbook,

$ pip install oci
$ ansible-galaxy collection install oracle.oci

Dynamic Inventory

The Oracle Ansible Inventory Plugin populates public Ubuntu instances.

The target Ubuntu instance must have the freeform tag ipfs_service: yes.

Configuration

1. Update inventory/oracle.oci.yml,
   1. Specify the region where you have deployed your server on Oracle Cloud. List of regions are at docs.oracle.com/en-us/iaas/Content/General/Concepts/regions.htm.
   2. Configure the authentication as per the Oracle Guide
2. Set username and SSH authentication in inventory/group_vars/

IPNS Initialization

IPNS derives the public URL from a keypair. Follow the instructions below to create a keypair.

Create a key using the following command and note the ID in the result,

$ ipfs key gen <name>

Export the key using the following command,

$ ipfs key export <name>

1. Save the ID and name in inventory/group_vars/tag_ipfs_service=yes.yml. Use inventory/group_vars/tag_ipfs_service=yes.yml.sample as a reference.
2. Save the exported key in the files directory.

Deployment

Run the playbook using the following command,

$ ./bin/apply.sh

Encryption

Encrypt sensitive files (IPFS key, SSH private keys and inventory/group_vars/tag_ipfs_service=yes.yml) before saving them. .gitignore must contain the unencrypted file paths.

Use the following command to decrypt the files after cloning the repository,

$ ./bin/decrypt.sh

Use the following command after running terraform to update the encrypted files,

$ ./bin/encrypt.sh <gpg key id>
