# Simple usage with a mounted data directory:
# > docker build -t simapp .
#
# Server:
# > docker run -it -p 26657:26657 -p 26656:26656 -v ~/.simapp:/root/.simapp simapp simd init test-chain
# TODO: need to set validator in genesis so start runs
# > docker run -it -p 26657:26657 -p 26656:26656 -v ~/.simapp:/root/.simapp simapp simd start
#
# Client: (Note the simapp binary always looks at ~/.simapp we can bind to different local storage)
# > docker run -it -p 26657:26657 -p 26656:26656 -v ~/.simappcli:/root/.simapp simapp simd keys add foo
# > docker run -it -p 26657:26657 -p 26656:26656 -v ~/.simappcli:/root/.simapp simapp simd keys list
