Description=IPFS daemon
After=network.target

# IMPORTANT! If you are running on a VPS/dedicated/similar
# `ipfs init --profile=server` or immediately after setting it up
# `ipfs profile apply server`.
# I would probably recommend `ipfs init --profile=badgerds && ipfs profile apply server`
# REF: https://github.com/ipfs/go-ipfs/issues/4343 "Running IPFS on VPS
# providers triggers netscan detection, risking account termination"

ExecStart=/home/mikaela/go/bin/ipfs daemon --routing=dhtclient --enable-gc --enable-namesys-pubsub

# My attempts at explaining flags above + --mount for fuse
# --mount - fuse for /ipfs and /ipns, see
#   https://github.com/ipfs/go-ipfs/blob/master/docs/fuse.md as it requires
#   some specific config, I am not setting it as default here.
# --routing=dhtclient - not serving requests to the network saving bandwidth
# --enable-gc - automatic cleaning of unpinned files per rules in ipfs
#   config, I think by default two hours or when the repo gets bigger than
#   10G
# --enable-namesys-pubsub - real time previously cached ipns updates
#
# My specific config:
#  ipfs config Reprovider.Strategy pinned - advertise only pinned files
#   to the network to reduce connections instead of also cached content
#   (which they will still be able to download, see ipfs/go-ipfs#4145)
#  ipfs config Swarm.ConnMgr.GracePeriod 1s - to get rid of excess
#   connections quickly
#  ipfs config --json Swarm.ConnMgr.HighWater 40 - attempt to stay below 40
#   connections
#  ipfs config --json Swarm.ConnMgr.LowWater 20 - attempt to keep at least
#   20 connections
#  ipfs config --json Swarm.EnableAutoRelay true - if impassable NAT is
#   detected, connect to the network through relays that have configured
#   themselves as open (EnableAutoNATService & EnableRelayHop?)
#  ipfs config --json Experimental.QUIC true - QUIC support, remember to
#   edit swarm addresses to include /ip4/0.0.0.0/udp/4001/quic
#   /ip6/::/udp/4001/quic
#  ipfs config --json Experimental.FilestoreEnabled true - for ipfs add
#   --nocopy to not store the content twice on disc
#
# Routing note: dhtclient may cause problems making the content findable
#               even if it uses less bandwitdh, so it may be better to use
#               dht everywhere if that isn't a problem. dht also breaks
#               LowWater/HighWater limits.
#
# I am using badger datastore.
#
#  Extra: to disable IPv4 connections:
#   ipfs swarm filters add /ip4/0.0.0.0/ipcidr/0
#    However I think this may do more harm than good, especially if the
#    other config options above (especially Reprovider.Strategy pinned) keep
#    amount of connection tolerable and won't cause issues.
