Estuary

An experimental ipfs node

Building

Requirements:

• go (1.15 or higher)
• jq
• hwloc
• opencl

1. Run make clean all inside the estuary directory

Running your own node

To run locally in a 'dev' environment, first run:

./estuary setup

Save the auth token that this outputs, you will need it for interacting with and controlling the node.

NOTE: if you want to use a different database than a sqlite instance stored in your local directory, you will need to configure that with the --database flag, passed before the setup command: ./estuary --database=XXXXX setup

Once you have the setup complete, choose an appropriate directory for estuary to keep its data, and use it as your datadir flag when running estuary. You will also need to tell estuary where it can access a lotus gateway api, we recommend using:

export FULLNODE_API_INFO=wss://api.chain.love

Then run:

./estuary --datadir=/path/to/storage --database=IF-YOU-NEED-THIS --logging

Running as daemon with Systemd

The Makefile has a target that will install a generic but workable systemd service for estuary.

Run make install-estuary-service on the machine you wish to run estuary on.

Make sure to follow the instructions output by the make command as configuration is required before the service can run succesfully.

Troubleshooting

Make sure to install all dependencies as indicated above. Here are a few issues that one can encounter while building estuary

Guide for: route ip+net: netlinkrib: too many open files

Error

If you get the following error:

/ERROR basichost basic/basic_host.go:328 failed to resolve local interface addresses {"error": "route ip+net: netlinkrib: too many open files"}

It is because you do not have enough open file handles available.

Solution

Update this with the following command:

ulimit -n 10000

Guide for: Missing hwloc on M1 Macs

The Portable Hardware Locality (hwloc) software package provides a portable abstraction of the hierarchical structure of current architectures, including NUMA memory nodes, sockets, shared caches, cores, and simultaneous multi-threading (across OS, versions, architectures, etc.).

lhwloc is used by libp2p-core. Estuary uses libp2p for the majority of its features including network communication, pinning, replication and resource manager.

Error

`ld: library not found for -lhwloc`

Solution

For M1 Macs, here's the following steps needed

• Step 1: brew install go bzr jq pkg-config rustup hwloc - Uninstall rust as it would clash with rustup in case you have installed.
• Step 2: export LIBRARY_PATH=/opt/homebrew/lib
• Step 3: Follow the steps as per the docs.

Guide for: cannot find -lfilcrypto collect2
