This is a guide on how to use docker containers to get mist up and running as per the Udemy course: https://www.udemy.com/blockchain-developer
This runs a few services that will be accessible to anyone else on your network. It is suggested that you only do this when you're on a secure network (e.g. home wifi).
- akhs/geth: An Ubuntu 16.04 image with the Ethereum C++ eth binaries installed.
- akhs/swarm: An Alpine 3.5 image with swarm.
First step is to install docker for mac:
https://www.docker.com/docker-mac
Once you've installed that and it's running on your system, open terminal and go into the directory where you want to create your chain data.
In that directory, create the genesis.json file that you want to use.
Next, we're going to boot a geth docker container and use it to initialize our chain data. We do that by running this command
docker container run --rm -v "$(pwd):/root/chaindata" -ti akhs/geth bash
The --rm option removes the container when we're done.
The -v "$(pwd):/root/chaindata" option binds your current directory to the /root/chaindata folder in the container.
The -ti option connects you to the container.
The akhs/geth specifies the image.
The bash executes instead of the default command, which allows you to connect and execute commands on the container.
If all goes according to plan, after executing the command, you should be presented with a prompt that says root@(random lettes/ numbers).
Initialize the chain by executing this command
geth init /root/chaindata/genesis.json --datadir /root/chaindata/
You should see some folders appear in your local folder (on your mac).
Now we will create an account, by executing this command:
geth --datadir=/root/chaindata account new
This will prompt you for a passphrase, which you'll need to remember for the next step. Also take note of the the address output, you'll need this as well:
Address: {7...}
You can now type exit to exit out of the container.
Now that we've set things up, we can start geth on our new network, by running this:
docker container run --rm -v "$(pwd):/root/chaindata" -p "8545:8545" akhs/geth
Now we neeed to boot the swarm image.
docker container run --rm -v "$(pwd):/root/chaindata" -p "8500:8500" -ti -e SWARM_ACCOUNT=(the account number from above - remove brackets) akhs/swarm
The -ti option allows you to interact with the output so you can type in your password
The -e SWARM_ACCOUNT=7... specifies the account number and is picked up by swarm
cd /Applications/Mist.app/Contents/MacOS
./Mist --rpc http://127.0.0.1:8545 --swarmurl http://127.0.0.1:8500
If you want to use the attach command, you can boot another geth image:
docker container run --rm -v "$(pwd):/root/chaindata" -ti akhs/geth bash
Then you can connect to geth with this command:
geth attach http://(the ip address of your computer on whatever network you're using):8545
We have enabled all of the APIs over the http rpc, so this will allow you to do whatever you want.
