Using [client.http](client.http) to explore the application!
# devcontainer setup
F1 in vscode and choose `Remote-Containers: Open Folder in Container...`, then waiting until it build sucessful
```bash
# check linux version
> cat /etc/os-release
# build all images of application
> docker compose build
```
Open a new tab
```bash
> cd local/
$ sudo chmod +x core-libs.sh start.sh
$ sudo ./core-libs.sh
# nomad cannot run on wsl2 image, then we need to work-around
$ sudo mkdir -p /lib/modules/$(uname -r)/
> echo '_/bridge.ko' | sudo tee -a /lib/modules/$(uname -r)/modules.builtin
# Start nomad and consul
> ./start.sh
```
Open another new tab
```bash
> cd nomad/jobs
> nomad job run traefik.nomad.hcl
> nomad job run postgresdb.nomad.hcl
> nomad job run rabbitmq.nomad.hcl
> nomad job run product-api.nomad.hcl
> nomad job run counter-api.nomad.hcl
> nomad job run barista-api.nomad.hcl
> nomad job run kitchen-api.nomad.hcl
```
Finally, you can play around using [client.http](client.http) to explore the application!
## Clean up
```bash
> nomad job stop kitchen-api.nomad.hcl
> nomad job stop barista-api.nomad.hcl
> nomad job stop counter-api.nomad.hcl
> nomad job stop product-api.nomad.hcl
> nomad job stop rabbitmq.nomad.hcl
> nomad job stop postgresdb.nomad.hcl
> nomad job stop traefik.nomad.hcl
```
# Troubleshooting
## Couldn't run `sebp/elk:latest` on Docker (Windows 11 - WSL2 with Docker for Desktop integrated)
> error: elasticsearch_1 | max virtual memory areas vm.max_map_count [65530] is too low, increase to at least [262144]
Jump into wsl2, then run command below
```
$ sudo sysctl -w vm.max_map_count=262144
```
Now, we can run `docker-compose up` again.
