# JFrog Artifactory Reverse Proxy Settings using Nginx
#### Reverse Proxy
* To use Artifactory as docker registry it's mandatory to use Reverse Proxy.
* Artifactory provides a Reverse Proxy Configuration Generator screen in which you can fill in a set of fields to generate
the required configuration snippet which you can then download and install directly in the corresponding directory of your reverse proxy server.
* To learn about configuring NGINX or Apache for reverse proxy refer to documentation provided on [JFrog wiki](https://www.jfrog.com/confluence/display/RTF/Configuring+a+Reverse+Proxy)
* By default Artifactory helm chart uses Nginx for reverse proxy and load balancing.
**Note**: Nginx image distributed with Artifactory helm chart is custom image managed and maintained by JFrog.
#### Features of Artifactory Nginx
* Provides default configuration with self signed SSL certificate generated on each helm install/upgrade.
* Persist configuration and SSL certificate in `/var/opt/jfrog/nginx` directory
#### Changing the default Artifactory nginx conf
Use a values.yaml file for changing the value of nginx.mainConf or nginx.artifactoryConf
These configuration will be mounted to the nginx container using a configmap.
For example:
1. Create a values file `nginx-values.yaml` with the following values:
```yaml
nginx:
artifactoryConf: |
ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3;
ssl_certificate {{ .Values.nginx.persistence.mountPath }}/ssl/tls.crt;
ssl_certificate_key {{ .Values.nginx.persistence.mountPath }}/ssl/tls.key;
ssl_session_cache shared:SSL:1m;
ssl_prefer_server_ciphers on;
## server configuration
server {
listen {{ .Values.nginx.internalPortHttps }} ssl;
listen {{ .Values.nginx.internalPortHttp }} ;
## Change to you DNS name you use to access Artifactory
server_name ~(?<repo>.+)\.{{ include "artifactory-ha.fullname" . }} {{ include "artifactory-ha.fullname" . }};
if ($http_x_forwarded_proto = '') {
set $http_x_forwarded_proto $scheme;
}
## Application specific logs
## access_log /var/log/nginx/artifactory-access.log timing;
## error_log /var/log/nginx/artifactory-error.log;
rewrite ^/$ /artifactory/webapp/ redirect;
rewrite ^/artifactory/?(/webapp)?$ /artifactory/webapp/ redirect;
if ( $repo != "" ) {
rewrite ^/(v1|v2)/(.*) /artifactory/api/docker/$repo/$1/$2 break;
}
rewrite ^/(v1|v2)/([^/]+)(.*)$ /artifactory/api/docker/$2/$1/$3;
rewrite ^/(v1|v2)/ /artifactory/api/docker/$1/;
chunked_transfer_encoding on;
client_max_body_size 0;
location /artifactory/ {
proxy_read_timeout 900;
proxy_pass_header Server;
proxy_cookie_path ~*^/.* /;
if ( $request_uri ~ ^/artifactory/(.*)$ ) {
proxy_pass http://{{ include "artifactory-ha.fullname" . }}:{{ .Values.artifactory.externalPort }}/artifactory/$1;
}
proxy_pass http://{{ include "artifactory-ha.fullname" . }}:{{ .Values.artifactory.externalPort }}/artifactory/;
proxy_set_header X-Artifactory-Override-Base-Url $http_x_forwarded_proto://$host:$server_port/artifactory;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
```
2. Install/upgrade artifactory:
```bash
helm upgrade --install artifactory-ha jfrog/artifactory-ha -f nginx-values.yaml
```
#### Steps to use static configuration for reverse proxy in nginx.
1. Get Artifactory service name using this command `kubectl get svc -n $NAMESPACE`
2. Create `artifactory.conf` file with nginx configuration. More [nginx configuration examples](https://github.com/jfrog/artifactory-docker-examples/tree/master/files/nginx/conf.d)
Following is example `artifactory.conf`
**Note**:
* Create file with name `artifactory.conf` as it's fixed in configMap key.
* Replace `artifactory-artifactory` with service name taken from step 1.
```bash
## add ssl entries when https has been set in config
ssl_certificate /var/opt/jfrog/nginx/ssl/tls.crt;
ssl_certificate_key /var/opt/jfrog/nginx/ssl/tls.key;
ssl_session_cache shared:SSL:1m;
ssl_prefer_server_ciphers on;
## server configuration
server {
listen 443 ssl;
listen 80;
## Change to you DNS name you use to access Artifactory
server_name ~(?<repo>.+)\.artifactory-artifactory artifactory-artifactory;
if ($http_x_forwarded_proto = '') {
set $http_x_forwarded_proto $scheme;
}
## Application specific logs
## access_log /var/log/nginx/artifactory-access.log timing;
## error_log /var/log/nginx/artifactory-error.log;
rewrite ^/$ /artifactory/webapp/ redirect;
rewrite ^/artifactory/?(/webapp)?$ /artifactory/webapp/ redirect;
if ( $repo != "" ) {
rewrite ^/(v1|v2)/(.*) /artifactory/api/docker/$repo/$1/$2 break;
}
rewrite ^/(v1|v2)/([^/]+)(.*)$ /artifactory/api/docker/$2/$1/$3;
rewrite ^/(v1|v2)/ /artifactory/api/docker/$1/;
chunked_transfer_encoding on;
client_max_body_size 0;
location /artifactory/ {
proxy_read_timeout 900;
proxy_pass_header Server;
proxy_cookie_path ~*^/.* /;
if ( $request_uri ~ ^/artifactory/(.*)$ ) {
proxy_pass http://artifactory-artifactory:8081/artifactory/$1 break;
}
proxy_pass http://artifactory-artifactory:8081/artifactory/;
proxy_set_header X-Artifactory-Override-Base-Url $http_x_forwarded_proto://$host:$server_port/artifactory;
proxy_set_header X-Forwarded-Port $server_port;
proxy_set_header X-Forwarded-Proto $http_x_forwarded_proto;
proxy_set_header Host $http_host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}
```
3. Create configMap of `artifactory.conf` created with step above.
```bash
kubectl create configmap art-nginx-conf --from-file=artifactory.conf
```
4. Deploy Artifactory using helm chart.
You can achieve this by providing the name of configMap created above to `nginx.customArtifactoryConfigMap` in [values.yaml](values.yaml)
Following is command to set values at runtime:
```bash
helm install --name artifactory-ha nginx.customArtifactoryConfigMap=art-nginx-conf jfrog/artifactory-ha
```
