Enable and configure SSL post installation

​

Enabling SSL

Because Package Security Manager does not require SSL certificates to operate, you’ll need to perform some additional steps in order to enable SSL on an existing HTTP based instance.

1. Open a terminal and connect to your instance of Package Security Manager.

2. Enter your installer directory (ate-installer-*).

   This directory contains both the docker-compose.yml and .env files.

3. Using your preferred file editor, open the docker-compose.yml file.

4. Find the services: nginx_proxy: section near the top of the file and add the following lines:

   secrets:
   - source: nginx_key
   target: /etc/nginx/certs/tls.key
   - source: nginx_cert
   target: /etc/nginx/certs/tls.crt
   

   For example:

   services:
   ...
       nginx_proxy:
         secrets:
         - source: nginx_key
         target: /etc/nginx/certs/tls.key
         - source: nginx_cert
         target: /etc/nginx/certs/tls.crt
   

5. Find the keycloak: environment: section further down in the file and add the following lines:

   - PROXY_ADDRESS_FORWARDING=true
   

6. Edit your .env file.

   1. Change DOMAIN to new FQDN, if applicable.
   2. Change NGINX_PROXY_PORT to 443.
   3. Change PROTOCOL to https

​

Configuring SSL

The following steps will allow you to configure the SSL:

1. Add or remove the following lines relating to the SSL in <BASE_DIR>/config/nginx/conf.d/repo.conf:

   By default, the <BASE_DIR> is /opt/anaconda/repo.

   listen              8080 ssl;
   listen              [::]:8080 ssl;
   
   ssl_certificate     /etc/nginx/certs/tls.crt;
   ssl_certificate_key /etc/nginx/certs/tls.key;
   ssl_protocols       TLSv1.2 TLSv1.3;
   ssl_ciphers         HIGH:!aNULL:!MD5;
   

2. Add or remove certificates from the <BASE_DIR>/config/nginx/certs directory.

3. Run the following commands:

   docker compose stop nginx_proxy
   docker compose up --detach
   

Refer to nginx’s documentation for the standard SSL configuration procedure.

Updating URL/URIs in Keycloak

Once your SSL cert and key are in place, you will need to update Keycloak to point to your new root URL and any valid URI redirects to your domain.

1. Navigate to your Keycloak instance at <FQDN>/auth/admin and log in.
2. Open the dropdown in the left-hand navigation and select the Anaconda Login (dev) realm.
3. Select Clients from the left-hand navigation.
4. Select repo-service from the list of available clients.
5. On the Settings tab, update your root URL and any necessary valid redirect URI’s.
6. Click Save at the bottom of the page.
7. Select Clients from the left-hand navigation.
8. Select repo-account-sync from the list of available clients.
9. On the Settings tab, update your root URL.
10. Click Save at the bottom of the page.

Rebuilding your channel index

Migrating from HTTP to HTTPS or updating your FQDN will alter the file path to your channel’s packages. You must rebuild your channel index to correct the file path. If you do not, you will be unable to successfully download packages after migrating.
