1. Copy contents of the terraform.tfvars.template to the terraform.tfvars and fill all variables
2. Set following variables to the environment:

PROVIDER - Cloud provider: `do` or `aws`
ENDPOINT - Endpoint of the ETH network with manager contract
NODES - Number of nodes to be created
SKALE_AMOUNT - Amount of SKALE tokens to transfer
ETH_AMOUNT- Amount of ETH to transfer
ETH_PRIVATE_KEY - Base ETH private key to send funds

bash run.sh

Ansible directory contains ansible provision for setuping skale node system.

Steps to run provision

1. Firstly you should create two nodes and attach external volume to it.
2. Install ansible on your machine.
3. Then you should copy inventory template from inventory/dev and fill it with absent fields.
4. Also you should add information about host that you cerated before
5. Run ansible-playbook -i path-to-your-inventory main.yaml

Recreates accounts from which sgx key will be configured.

ansible-playbook -i path-to-your-inventory wallet.yaml

Setups node on remove server:

1. Uploads sources.
2. Reinstalls skale-cli.
3. Runs skale node init.
4. Registers node on manager.

ansible-playbook -i path-to-your-inventory setup.yaml

Installs needed dependecies and setups os configs.

ansible-playbook -i path-to-your-inventory base.yaml

Destroys all containers, removes .skale, reruns setup.yaml steps.

ansible-playbook -i path-to-your-inventory restart.yaml 

Destroys all containers, removes .skale, reruns setup.yaml steps.

ansible-playbook -i path-to-your-inventory restart.yaml 

Recreates accounts and runs restart.yaml steps.

ansible-playbook -i path-to-your-inventory restart.yaml 

Required variables in the inventory:

manager_tag=''
eth_private_key=''
endpoint=''
deploy_gas_price=''

aws_key='' # for S3 upload
aws_secret='' # for S3 upload

Deploy and upload ABIs to AWS S3:

ansible-playbook -i inventory deploy_contracts.yaml

Deploy only:

ansible-playbook -i inventory deploy_contracts.yaml --tags deploy_contracts

Upload only (from helper-scripts/contracts_data/manager.json):

ansible-playbook -i inventory deploy_contracts.yaml --tags upload_contracts

1. Copy cert.pem and privkey.pem files to the ansible/files directory
2. Run:

ansible-playbook -i path-to-your-inventory ssl.yaml 

1. add authorized_keys file with all id_rsa.pub what you want to add for access on nodes to the ansible/files directory
2. Run:

ansible-playbook -i path-to-your-inventory upload_authorized_keys.yaml 

ansible-playbook -i inventory main.yaml --skip-tags deploy_ima,upload_ima

1. Create if not exists virtual env for python 3.7 or higher in root of project and activate she before script start
2. Run from root of roject:

pip install -r skale-nodes/ansible/requirements.txt

3. copy inventory-template like inventory and fill dev file with absent fields.
4. Add node_ips.json file with all ips what you want (example {"node_name": "node_ip", ..., "node_name": "node_ip"}) to the ansible/files directory
5. Go to skale-nodes/ansible dir and run:

bash utils/generate_hosts.sh

ansible-playbook -i inventory run_monitor.yaml
