# PoC SDL for running nym-mixnode on Akash Network
# https://twitter.com/andy83482/status/1665093815290437635
#
# Provider requires to support the IPv6, steps outlined here https://github.com/akash-network/support/issues/100
#
# apt update
# apt -y install wget curl jq iproute2 iputils-ping net-tools netcat-openbsd
# wget -c "https://github.com/nymtech/nym/releases/download/nym-binaries-v1.1.19/nym-mixnode"
# chmod +x nym-mixnode
# install nym-mixnode /usr/local/bin/
# now restore the PEM files from the backup so that "nym-mixnode init" won't create the new ones: ~/.nym/mixnodes/<node-id>/data/*.pem
# IMPORTANT: make sure "--host ::" so that mixnode accepts both IPv4 and IPv6! Host & K8s cluster have to support IPv6 and K8s has to support IPv6DualStack
# mixnode1.akash.pro should point to A, AAAA DNS records
# nym-mixnode init --id seventh-horizon --wallet-address n1n8damnwuweg7jdq28xfpyn6mtwkpx4c8v7cx0j --host :: --announce-host mixnode1.akash.pro
#
# nym-mixnode describe --id seventh-horizon
# ulimit -n 65535; exec nym-mixnode run --id seventh-horizon > logs 2>&1 &
#
# Verify:
# # cat /proc/$(pidof -s nym-mixnode)/limits | grep 'open files'
# Max open files            65535                65535                files
#
# IMPORTANT: backup the PEM files!!! ~/.nym/mixnodes/<node-id>/data/*.pem
#
# Make sure to update the mapped ports [Mix Port, Verloc Port, HTTP Port], Host and Version (if not using IP Leasing) on the Nyx chain in your Node Settings (via Nym Wallet -> Bonding -> your mix node -> Node Settings)
#
# Verify:
# curl -sk <mixnode-IP>:<HTTP Port>/stats | jq
# curl -sk <mixnode-IP>:<HTTP Port>/verloc | jq | head -5
# curl -sk <mixnode-IP>:<HTTP Port>/hardware | jq
# curl -sk <mixnode-IP>:<HTTP Port>/description | jq
