# Kafka playtime
[Progress tracking](https://github.com/mdub/kafka-playtime/projects/1)
# Running on Linux
Prefix commands with `sudo` due to the docker daemon running as `root`.
There seems to be [a bug with docker-compose](https://github.com/docker/compose/issues/4076#issuecomment-324932294) where it takes ~40ms to connect to the terminal output of the container, so stuff logged to the terminal in this time is lost. The best workaround seems to be adding a delay of 0.1 seconds like so:
```bash
sudo ./auto/dev sh -c 'sleep 0.1; scripts/publish'
```
## Setup
```bash
./auto/dev/setup
```
## Usage
### Shell
To open a shell in the console container that has the Kafka management utils:
```bash
./auto/dev/console
```
### Watch events
To watch all raw events, starting from the beginning:
```bash
./auto/dev/console scripts/watch
```
### Watch robot commands (same as events)
To watch all raw events, from now onwards:
```bash
./auto/dev/robctl watch commands
```
Starting from the beginning:
```bash
./auto/dev/robctl watch commands --history
```
### Watch board
To watch the toy robot world, viewing the board and all robots:
```bash
./auto/dev/robctl watch world
```
### Control a robot
To control a robot:
```bash
./auto/dev/robctl control ROBOT_NAME
```
Valid commands are:
```
place 0 0 s
place 4 4 n
move
left
right
```
