Install from scratch

Run the following commands to clone the repository and set everything up:

git clone https://github.com/StakeSquid/graphprotocol-testnet-docker
cd graphprotocol-testnet-docker
git submodule init
git submodule update
git config --global user.email "[email protected]"
git config --global user.name "Example User"
git branch --set-upstream-to=origin

Get a domain

To enable SSL on your host you should get a domain.

You can use any domain and any regsitrar that allowes you to edit DNS records to point subdomains to your IP address.

For a free option go to myFreenom and find a free domain name. Create a account and complete the registration.

In the last step choose "use dns" and enter the IP address of your server. You can choose up to 12 months for free.

Under "Service > My Domains > Manage Domain > Manage Freenom DNS" you can add more subdomains later.

Create 4 subdomains, named as follows:

index.sld.tld
prometheus.sld.tld
grafana.sld.tld

Create a mnemonic

You need a wallet with a seed phrase that is registered as your operator wallet. This wallet will be the one that makes transactions on behalf of your main wallet (which holds and stakes the GRT).

The operator wallet has limited functionality, and it's recommended to be used for security reasons.

You need a 12-word, or 15-word mnemonic phrase in order for it to work.

To make yourself a mnemonic eth wallet you can go to this website, select ETH from the dropdown and press generate.

You get a seed phrase in the input field labeled BIP39 Mnemonic.

You can find your address, public key and private key in the first row of the table if you scroll down the page in the section with the heading "Derived Addresses".

Make sure you save the mnemonic, private key and the wallet address somewhere safe.

If you need, you can import the wallet using the private key into Metamask

Configure the environment variables

Edit the file called .env and add your values to the following envs:

[email protected]
INDEX_HOST=index.sld.tld
QUERY_HOST=query.sld.tld
GRAFANA_HOST=dashboard.sld.tld
ADMIN_USER=your_user
ADMIN_PASSWORD=your_password
DB_USER=your_db_user
DB_PASS=your_db_password
GRAPH_NODE_DB_NAME=your_graphnode_db_name
AGENT_DB_NAME=your_agent_db_name
CHAIN_0_NAME="network-name"
CHAIN_0_RPC="http://ip:port"
TXN_RPC="http://ip:port"
OPERATOR_SEED_PHRASE="12 or 15 word mnemonic"
STAKING_WALLET_ADDRESS=0xAdDreSs
GEO_COORDINATES='69.420 69.420'
INDEXER_AGENT_OFFCHAIN_SUBGRAPHS=""


#The following ENV vars are optional
#they need to be added above the last line

#QUERY_FEE_REBATE_CLAIM_THRESHOLD=number-in-grt \
#REBATE_CLAIM_BATCH_THRESHOLD=number-in-grt \
#NETWORK_SUBGRAPH_DEPLOYMENT=QmTePWCvPedmVxAvPnDFmFVxxYNW73z6xisyKCL2xa5P6e \
#INDEXER_AGENT_OFFCHAIN_SUBGRAPHS="Qm,Qm,Qm" \
#GRAPHNODE_LOGLEVEL=warn \
#ETHEREUM_TRACE_STREAM_STEP_SIZE=100 \
#ETHEREUM_BLOCK_BATCH_SIZE=50 \
#ETHEREUM_RPC_MAX_PARALLEL_REQUESTS=128 \
#GRAPH_ETHEREUM_MAX_BLOCK_RANGE_SIZE=1000 \
#GRAPH_ETHEREUM_TARGET_TRIGGERS_PER_BLOCK_RANGE=500 \
#INDEXER_AGENT_GAS_PRICE_MAX=gas-price-in-gwei \

Required env vars:

  • EMAIL - only used as contact to create SSL certificates. Usually it doesn't receive any emails but is required by the certificate issuer.
  • INDEX_HOST - your indexer public endpoint. The gateway will be sending queries to this endpoint.
  • QUERY_HOST - your query public playground. You can use this endpoint to send test queries directly into your Graph infrastructure to see if everything works properly. This env var is not present on the Mainnet Docker build.
  • GRAFANA_HOST - your Grafana dashboard for indexer stack monitoring.
  • ADMIN_USER and ADMIN_PASSWORD - will be used by Grafana, Prometheus and AlertManager.
  • DB_USER and DB_PASS - will be used for initializing the PostgreSQL Databases (both index/query DB and indexer agent/service DB).
  • GRAPH_NODE_DB_NAME - the name of the database used by the Index/Query nodes.
  • AGENT_DB_NAME - the name of the database used by the Indexer agent/service nodes.
  • CHAIN_0_NAME - the name of the network that you want to index
  • `CHAIN_0_RPC - your RPCs (archive nodes) used by the index nodes.
  • TXN_RPC - your Goerli ETH RPC used by Indexer agent/service nodes. This can be a fast/full/archive node, up to you! Please note that using Erigon as the TXN_RPC has proven unreliable by some indexers.
  • OPERATOR_SEED_PHRASE - the 12/15 word mnemonic that you generated earlier. Will be used by the Agent/Service to send transactions (open/close allocations, etc)
  • STAKING_WALLET_ADDRESS - the address (0x...) that you staked your GRT with, ideally living on an entirely different mnemonic phrase than your Operator Wallet.
  • GEO_COORDINATES of your server - you can search for an ip location website and check your server exact coordinates.

Optional env vars:

  • QUERY_FEE_REBATE_CLAIM_THRESHOLD - the minimum amount of GRT to claim per allocation
  • REBATE_CLAIM_BATCH_THRESHOLD - the minimum amount of Total GRT to batch claim for all allocations combined
  • NETWORK_SUBGRAPH_DEPLOYMENT - The Mainnet Network Subgraph IPFS hash, used if you want to rely on your own subgraph deployment rather than the gateways subgraphs
  • INDEXER_AGENT_OFFCHAIN_SUBGRAPHS - Gives you the possibility of syncing subgraphs locally without allocating to them onchain
  • GRAPHNODE_LOGLEVEL - the log level of the graph-node (indexer/query) - trace/debug/info/warn/error - if you have a whackton of subgraphs, increasing the loglevel to warn/error helps lowering the indexing time
  • ETHEREUM_TRACE_STREAM_STEP_SIZE - this helps (or not) indexing times by very small margins - use at own risk
  • ETHEREUM_BLOCK_BATCH_SIZE - this helps (or not) indexing times by very small margins - use at own risk
  • ETHEREUM_RPC_MAX_PARALLEL_REQUESTS - this helps (or not) indexing times by very small margins - use at own risk
  • GRAPH_ETHEREUM_MAX_BLOCK_RANGE_SIZE - this helps (or not) indexing times by very small margins - use at own risk
  • GRAPH_ETHEREUM_TARGET_TRIGGERS_PER_BLOCK_RANGE - this helps (or not) indexing times by very small margins - use at own risk
  • INDEXER_AGENT_GAS_PRICE_MAX - the maximum Gas Price (GWEI) that the indexer-agent will attempt to send transactions with

Note: If you want to use any of the optional env vars, you need to copy the line that you want to enable above the last line, and uncomment it.

Containers:

  • Graph Node (query node)
  • Graph Node (index node)
  • Indexer Agent
  • Indexer Service
  • Indexer CLI
  • Postgres Database for the index/query nodes
  • Postgres Database for the agent/service nodes
  • Prometheus (metrics database) http://<host-ip>:9090
  • Prometheus-Pushgateway (push acceptor for ephemeral and batch jobs) http://<host-ip>:9091
  • AlertManager (alerts management) http://<host-ip>:9093
  • Grafana (visualize metrics) http://<host-ip>:3000
  • NodeExporter (host metrics collector)
  • cAdvisor (containers metrics collector)
  • Caddy (reverse proxy and basic auth provider for prometheus and alertmanager)

Additional configs and details:

Start

To start, all you need to do is to:

bash start

Be aware that initially it takes several minutes to download and run all the containers (especially the cli container, that one takes a while to build), so be patient. :)

Subsequent restarts will be much faster.

In case something goes wrong, find the problem, edit the variables, and add --force-recreate at the end of the command, plus the container you want to recreate:

bash start --force-recreate <container_name>

Or to recreate the entire stack:

bash start --force-recreate

Verify that it runs properly

To verify that everything is up and running, you need to:

docker ps

And look for containers that are crash looping - you will notice restarting and a countdown - that means those containers are not working properly.

To further debug, try looking for the container logs and see what they say. More information in the troubleshooting section.

Install or Update the Agora and Qlog modules

To update those repos to the latest version just do the following command occasionally.

git submodule update

To use qlog or agora execute the runqlog or runagora scripts in the root of the repository.

./runagora --help
./runqlog --help

This will use the compiled qlog tool and extract queries since yesterday or 5 hours ago and store them to the query-logs folder.

./extract_queries_since yesterday
./extract_queries_since "5 hours ago"

To make journald logs persistent across restarts you need to create a folder for the logs to store in like this:

mkdir -p /var/log/journal

Updates and Upgrades

The general procedure is the following:

cd <project-folder>
git fetch
git pull

This will update the scripts from the repository.

To upgrade the containers:

bash start --force-recreate

To update Agora or Qlog repos to the latest version just do the following command occasionally:

git submodule update

To use qlog or agora execute the runqlog or runagora scripts in the root of the repository.

./runagora --help
./runqlog --help
