# Tendermint P2P Tests
|
|
|
|
These scripts facilitate setting up and testing a local testnet using docker containers.
|
|
|
|
Setup your own local testnet as follows.
|
|
|
|
For consistency, we assume all commands are run from the Tendermint repository root (ie. $GOPATH/src/github.com/tendermint/tendermint).
|
|
|
|
First, build the docker image:
|
|
|
|
```
|
|
docker build -t tendermint_tester -f ./test/docker/Dockerfile .
|
|
```
|
|
|
|
Now create the docker network:
|
|
|
|
```
|
|
docker network create --driver bridge --subnet 172.57.0.0/16 my_testnet
|
|
```
|
|
|
|
This gives us a new network with IP addresses in the rage `172.57.0.0 - 172.57.255.255`.
|
|
Peers on the network can have any IP address in this range.
|
|
For our four node network, let's pick `172.57.0.101 - 172.57.0.104`.
|
|
Since we use Tendermint's default listening port of 46656, our list of seed nodes will look like:
|
|
|
|
```
|
|
172.57.0.101:46656,172.57.0.102:46656,172.57.0.103:46656,172.57.0.104:46656
|
|
```
|
|
|
|
Now we can start up the peers. We already have config files setup in `test/p2p/data/`.
|
|
Let's use a for-loop to start our peers:
|
|
|
|
```
|
|
for i in $(seq 1 4); do
|
|
docker run -d \
|
|
--net=my_testnet\
|
|
--ip="172.57.0.$((100 + $i))" \
|
|
--name local_testnet_$i \
|
|
--entrypoint tendermint \
|
|
-e TMHOME=/go/src/github.com/tendermint/tendermint/test/p2p/data/mach$i/core \
|
|
tendermint_tester node --seeds 172.57.0.101:46656,172.57.0.102:46656,172.57.0.103:46656,172.57.0.104:46656 --proxy_app=dummy
|
|
done
|
|
```
|
|
|
|
If you now run `docker ps`, you'll see your containers!
|
|
|
|
We can confirm they are making blocks by checking the `/status` message using `curl` and `jq` to pretty print the output json:
|
|
|
|
```
|
|
curl 172.57.0.101:46657/status | jq .
|
|
```
