Hi Everyone!  
So far I’ve managed to run the cert-viewer, the cert-tool to create and manage certificates, and the cert-issuer but only in the docker image and on regtest mode.  
Does anyone know how to configure the bitcoin client in the docker image to change it to testnet? I havent found the Bitcoin.conf file, so I created one and place it in the “bitcoin” folder, but that didnt change from regtest to testnet.  
The other thing I’ve tried is to run the cert-isuer outside the docker image, but Im getting the “Not enough satoshis” error even though there are plenty in my bitcoin-cli runing on my pc. Does anyone know how can I connect the Issuer to my bitcoin client?  
Thanks in advance  
Julian

Typically when running from the docker image, you’ll run testnet/mainnet in broadcast mode, without using bitcoind. Check out [this link to our wiki](https://github.com/blockchain-certificates/cert-issuer#configuring-cert-issuer) for more info on setting up the cert-issuer config.

For setting up with a local bitcoind, follow these instructions: [https://github.com/blockchain-certificates/cert-issuer/blob/master/docs/bitcoind.md#local-bitcoin-node-instructions](https://github.com/blockchain-certificates/cert-issuer/blob/master/docs/bitcoind.md#local-bitcoin-node-instructions)

If those don’t help, let us know.
