+First let's exchange our user's API key for an infratographer JWT.

+
+#+RESULTS:
+
+
+If all went well, you should see a json object containing the =loadbalancers= key from this block.

+** Creating a LB
+
+Here we'll create an empty LB with our newly exchanged API key.

+  curl -s \

+#+RESULTS:

+: > > > {
+:   "errors": null,
+:   "id": "loadbal-ygZi9cUywLk5_oAoLGMxh"
+: }
+
+
+All we have is an ID now, but eventually we should get an IP back.
+#+begin_src shell
+  RES=$(curl -s \

+  echo $LOADBALANCER_ID
+#+end_src
+
+#+RESULTS:
+:
+: > > > loadbal-ygZi9cUywLk5_oAoLGMxh
+
+
+** Create the backends
+
+The load balancer requires a pool with an associated origin.
+
+#+begin_src shell
+  export POOL_ID=$(curl -s -H"Authorization: Bearer $INFRA_TOK" \
+			-H"content-type: application/json" \
+			-d '{"name": "pool9", "protocol": "tcp"}' \

+
+
+Let's create a LB that points to =icanhazip.com= so we can see how we're proxying
+
+#+begin_src shell

+  data=$(jq -M -c -n --arg port_id $POOL_ID --arg target_ip "$TARGET_IP" '{"name": "icanhazip9", "target": $target_ip, "port_id": $port_id, "port_number": 80, "active": true}' | tee )
