To deploy to the testnet, you need to first have account on the testnet with some ether on it.
If you dont have an account already, you can create one already with
geth account new
It will ask you for a password, and will return the account address.
You can then edit config/blockchain.yml and add your address.
for e.g if the address is 0x12345, then:
# config/blockchain.yml
...
staging:
rpc_host: localhost
rpc_port: 8101
rpc_whitelist: "*"
datadir: default
network_id: 0
console: true
account:
init: false
address: 0x12345
The key things are that the networkid be 0 (which is the identifier of the testnet) and the address is set.
Embark will ask you for your password, If you don't want to input the password everytime. You can add it to a file for e.g config/staging_password and then add this to the environment configuration:
# config/blockchain.yml
...
staging:
rpc_host: localhost
rpc_port: 8101
rpc_whitelist: "*"
datadir: default
network_id: 0
console: true
account:
init: false
address: 0x12345
password: config/staging_password
Afterwards wherever you specify the staging environment in your embark commands, it will use the testnet. e.g
Usual deployment:
embark blockchain staging
embark run staging
Deploy only contracts:
embark deploy staging
Build and Deploy app:
embark build staging
Release to IPFS:
embark ipfs staging
