### Configuring local ElasticSearch instance
Start local ElasticSearch instance using docker:
```sh
mkdir -p $(pwd)/data/elasticsearch
sudo chown -R 1000:1000 $(pwd)/data/elasticsearch
docker run --rm -p 127.0.0.1:9200:9200 -p 127.0.0.1:9300:9300 -e "discovery.type=single-node" -v "$(pwd)/data/elasticsearch:/usr/share/elasticsearch/data" docker.elastic.co/elasticsearch/elasticsearch:7.16.3
```
Configure `app.ini`:
```ini
[indexer]
ISSUE_INDEXER_TYPE = elasticsearch
ISSUE_INDEXER_CONN_STR = http://elastic:changeme@localhost:9200
REPO_INDEXER_ENABLED = true
REPO_INDEXER_TYPE = elasticsearch
REPO_INDEXER_CONN_STR = http://elastic:changeme@localhost:9200
```
### Building and adding SVGs
SVG icons are built using the `make svg` target which compiles the icon sources defined in `build/generate-svg.js` into the output directory `public/img/svg`. Custom icons can be added in the `web_src/svg` directory.
