# Local Cluster with Docker Compose
|
|
|
|
## Requirements
|
|
|
|
- [Install gaia](/docs/index.rst)
|
|
- [Install docker](https://docs.docker.com/engine/installation/)
|
|
- [Install docker-compose](https://docs.docker.com/compose/install/)
|
|
|
|
## Build
|
|
|
|
Build the `gaiad` binary and the `tendermint/gaiadnode` docker image.
|
|
|
|
Note the binary will be mounted into the container so it can be updated without
|
|
rebuilding the image.
|
|
|
|
```
|
|
cd $GOPATH/src/github.com/cosmos/cosmos-sdk
|
|
|
|
# Build the linux binary in ./build
|
|
make build-linux
|
|
|
|
# Build tendermint/gaiadnode image
|
|
make build-docker-gaiadnode
|
|
```
|
|
|
|
|
|
## Run a testnet
|
|
|
|
To start a 4 node testnet run:
|
|
|
|
```
|
|
make localnet-start
|
|
```
|
|
|
|
The nodes bind their RPC servers to ports 46657, 46660, 46662, and 46664 on the host.
|
|
This file creates a 4-node network using the gaiadnode image.
|
|
The nodes of the network expose their P2P and RPC endpoints to the host machine on ports 46656-46657, 46659-46660, 46661-46662, and 46663-46664 respectively.
|
|
|
|
To update the binary, just rebuild it and restart the nodes:
|
|
|
|
```
|
|
make build-linux
|
|
make localnet-stop
|
|
make localnet-start
|
|
```
|
|
|
|
## Configuration
|
|
|
|
The `make localnet-start` creates files for a 4-node testnet in `./build` by calling the `gaiad testnet` command.
|
|
|
|
The `./build` directory is mounted to the `/gaiad` mount point to attach the binary and config files to the container.
|
|
|
|
For instance, to create a single node testnet:
|
|
|
|
```
|
|
cd $GOPATH/src/github.com/cosmos/cosmos-sdk
|
|
|
|
# Clear the build folder
|
|
rm -rf ./build
|
|
|
|
# Build binary
|
|
make build-linux
|
|
|
|
# Create configuration
|
|
docker run -v `pwd`/build:/gaiad tendermint/gaiadnode testnet --o . --v 1
|
|
|
|
#Run the node
|
|
docker run -v `pwd`/build:/gaiad tendermint/gaiadnode
|
|
|
|
```
|
|
|
|
## Logging
|
|
|
|
Log is saved under the attached volume, in the `gaiad.log` file and written on the screen.
|
|
|
|
## Special binaries
|
|
|
|
If you have multiple binaries with different names, you can specify which one to run with the BINARY environment variable. The path of the binary is relative to the attached volume.
