# Description

First make sure to have a stable guix checkout. E.g.

```
gn3@tux01:~/production/gn-proxy$ /home/wrk/opt/guix-pull/bin/guix pull -p ~/opt/guix-pull
```

In addition to gn1 and gn2 we have 3 running gn3 services:

## gn-proxy - deployed as gn3 user in production

gn-proxy runs in systemd. See

=> https://github.com/genenetwork/gn-proxy/blob/master/.guix-run
=> https://github.com/genenetwork/gn-proxy/blob/master/extra/guix-gn-proxy.service

Test with

```
curl localhost:8080/version
{"version":"0.2.1"}

curl https://genenetwork.org/gn3-proxy/version
{"version":"0.2.1"}
```

To deploy by hand use

```
su gn3
alias guix=~/opt/guix/bin/guix
gn3@tux01:~/production/gn-proxy
source .guix-deploy
raco pkg install --auto
env TMPDIR=/home/gn3/tmp SQL_USER=*** SQL_PASSWORD=*** racket -L info server/rest.rkt
```


## gn3 aliases

=> https://github.com/genenetwork/gn3/blob/master/.guix-run
=> https://github.com/genenetwork/gn3/blob/master/etc/gn3-aliases.service

Test with

```
curl http://localhost:8000/gene/aliases/BRCA2
["FACD","FAD","FANCD","BROVCA2","FAD1","FANCD1","BRCC2","GLM3","PNCA2","XRCC11"]

curl http://localhost:8000/
[ "Hello GeneNetwork3!"  ]

curl https://genenetwork.org/gn3
[ "Hello GeneNetwork3!"  ]

curl https://luna.genenetwork.org/gn3/
[ "Hello GeneNetwork3!"  ]
```

## genenetwork3 (python3)

If the menu does not load, this is the culprit. It should be an external API link.


```
gn3@tux02:~/production/genenetwork3$ env GUIX_PACKAGE_PATH=~/guix-bioinformatics/ ~/opt/guix-gn3/bin/guix shell -C -D --network --expose=/home/gn2/production/genotype_files/ -f guix.scm -- gunicorn --bind 0.0.0.0:8087 --workers 8 --keep-alive 6000 --max-requests 10 --max-requests-jitter 5 --timeout 1200 wsgi:app
```

Test with

```
curl localhost:8087/api/version
"1.0"
curl localhost:8087/api/menu/generate/json
...
curl https://genenetwork.org/api3/api/version
"1.0"
curl https://genenetwork.org/api3/api/menu/generate/json
tomato
curl -L https://luna.genenetwork.org/api3/version
"1.0"
```

note the menu is more recent GN3.

On epysode:

```
http://mars.genenetwork.org/gn3/api/version
"1.0"
http://gn2-fallback.genenetwork.org/gn3/api/menu/generate/json
tomato
```

## Notes

We track services now on

=> https://rabbit.genenetwork.org/sheepdog/index.html

## System container

```
systemctl stop genenetwork-development-container
mv /var/guix-containers /export2
systemctl start genenetwork-development-container
```

The commit that changes the mounts is at
