• The username and password from Step 1: VPN in the IP Plan.

To protect the environment, MacStadium deploys the Orka cluster with a dedicated Cisco Adaptive Security Virtual Appliance (ASAv) firewall. Cisco ASAv runs the same software as physical Cisco ASAs and delivers full ASA firewall and VPN capabilities to the cloud.

TIP: Looking for more information about your firewall?

See MacStadium Docs: Firewall Overview and MacStadium Docs: Logging into Cisco Firewall.

The Orka cluster sits behind its dedicated Cisco ASAv firewall, which must be connected to the cluster via VPN to do any of the following tasks:

• Manage the Orka VMs and K8s pods.
• Log in to the firewall and manage connectivity between the cluster and the outside world (for example, enterprise networks, other private and public clouds).

MacStadium has pre-configured the firewall and has enabled VPN access. Simply run a VPN client and provide the server address and credentials for the connection.

(Open-source option) OpenConnect

Why OpenConnect?

For pre-dominantly CLI users, consider using OpenConnect - an open-source VPN client available from the command line.

• Download and install
• Configure OpenConnect to access Orka via custom domain
• Use OpenConnect

Download and install OpenConnect

• If Homebrew is enabled on the system, then run brew install openconnect from the command line.
• Windows users, can download and build the OpenConnect package or use Cisco AnyConnect instead.

Configure OpenConnect to access Orka via custom domain

To be able to reach the custom Orka domain API endpoint, add a DNS server to the network configuration.

📘

What's the DNS address?

The DNS server address is the .251 address for the Private-1 network from the IP Plan. For example: 10.10.10.251 or 10.221.188.251.

macOS

1. Go to System Preferences > Network.
2. From the list of network connections, select the current Internet connection, locate and click the Advanced... button at the right bottom corner of the dialog.
3. Go to the DNS tab.
4. At the bottom of the DNS Servers list, click +.
5. Type the Orka DNS address and press Enter.
6. If not already at the top, drag and drop the Orka DNS server to the top. It must be the first item in the list.
7. Click OK, click Apply, and exit System Preferences.

Linux

1. Use a text editor to open /etc/resolv.conf.
2. Locate the nameserver section and add the Orka DNS address:

nameserver <ORKA-DNS-ADDRESS>

3. Make sure that this is the first nameserver entry in the list.

Windows

1. Go to Control Panel > Network and Internet.
2. Under Network and Sharing Center, select View network and status.
3. In the Network and Sharing Center, in the sidebar, select Change adapter settings.
4. In the Network Connections window, right-click the current Internet connection and select Properties.
5. Go to the Networking tab, scroll down and click Internet Protocol Version 4 (TCP/IPv4).
6. With Internet Protocol Version 4 (TCP/IPv4) highlighted, click Properties.
7. Go to the General tab and select Use the following DNS server addresses.
8. Add the Orka DNS server as the Preferred DNS server. Add any other name server as the Alternate DNS server (for example, 8.8.8.8).
9. Click OK .
10. Click Close.

Use OpenConnect

1. From the command line, run the following command. Replace <SERVER ADDRESS> with the server address from Step 1: VPN in the IP Plan.

sudo openconnect <SERVER ADDRESS> --protocol=anyconnect
// OR if running on Windows
openconnect <SERVER ADDRESS> --protocol=anyconnect

2. Follow the prompts.
   • On the immediate Password prompt, provide the sudo password (the password for the current computer user) and press Enter.
   • On the Enter 'yes' to accept, 'no' to abort; anything else to view: prompt, type yes and press Enter.
   • On the Username prompt, provide the username from Step 1: VPN in the IP Plan and press Enter.
   • On the Password prompt, provide the password from Step 1: VPN in the IP Plan and press Enter.

When the connection is established, a similar output (show below) appears:
