# mknet
|
||||
|
||||
## Installation
|
||||
mknet is a tool to simulate various network topologies
|
||||
locally thanks to network namespaces and traffic control (tc).
|
||||
|
||||
## Prepare your environment
|
||||
|
||||
Get the repository and its submodules:
|
||||
|
||||
```bash
|
||||
sudo pip3 install git+https://git.deuxfleurs.fr/trinity-1686a/mknet
|
||||
git clone https://git.deuxfleurs.fr/Deuxfleurs/mknet.git
|
||||
cd mknet
|
||||
git submodule update --init
|
||||
```
|
||||
|
||||
## Usage
|
||||
Compile benchmark tools:
|
||||
|
||||
```bash
|
||||
sudo rm -rf /tmp/garage-testnet/ # always start by deleting previous run
|
||||
sudo mknet create ./config.yml
|
||||
sudo mknet run-all example/deploy_garage.sh
|
||||
sudo mknet run dc1:dc1s1 garage -c /tmp/garage-testnet/dc1/dc1s1/garage.toml status
|
||||
sudo mknet destroy
|
||||
( cd benchmarks/warp && go build )
|
||||
( cd benchmarks/s3concurrent && go build )
|
||||
( cd benchmarks/s3lat && go build )
|
||||
```
|
||||
|
||||
## Instrumented daemons
|
||||
|
||||
If you want to use the scripts provided in the `example` folder,
|
||||
you must add to your path some tools.
|
||||
|
||||
### Garage (`deploy_garage.sh`)
|
||||
Switch to root as it is required by our tool,
|
||||
and setup your python environment.
|
||||
|
||||
```bash
|
||||
# see versions on https://garagehq.deuxfleurs.fr/_releases.html
|
||||
export GRG_ARCH=x86_64-unknown-linux-musl
|
||||
export GRG_VERSION=v0.5.0
|
||||
|
||||
sudo wget https://garagehq.deuxfleurs.fr/_releases/${GRG_VERSION}/${GRG_ARCH}/garage -O /usr/local/bin/garage
|
||||
sudo chmod +x /usr/local/bin/garage
|
||||
|
||||
garage help
|
||||
sudo -i
|
||||
pip3 install --user .
|
||||
( cd scenarios && pip3 install -r requirements.txt )
|
||||
```
|
||||
|
||||
### Minio (`deploy_minio.py`)
|
||||
## Run a test
|
||||
|
||||
```
|
||||
sudo wget https://dl.min.io/server/minio/release/linux-amd64/minio -O /usr/local/bin/minio
|
||||
sudo chmod +x /usr/local/bin/minio
|
||||
(Not yet implemented)
|
||||
|
||||
```bash
|
||||
./mknet scenario ./benchmarks/garage-s3lat ./topo/single-dc.yml
|
||||
```
|
||||
|
||||
## Manual usage
|
||||
|
||||
```bash
|
||||
./mknet create ./topo/with-vdsl.yml
|
||||
./mknet run-all ./scenarios/garage-manual
|
||||
./mknet run dc1:dc1s1 /tmp/mknet-bin/garage* -c /tmp/mknet-store/garage/dc1/dc1s1/garage.toml status
|
||||
./mknet run-all ./scenarios/clean
|
||||
./mknet destroy
