Quick deployment

Step 1: Clone repository:

git clone https://github.com/polkascan/polkascan-os.git

Step 2: Change directory:

cd polkascan-os

Step 3: Check available releases:

git tag

Step 4: Checkout latest releases:

git checkout v0.x.x

Step 5: Make sure to also clone submodules within the cloned directory:

git submodule update --init --recursive

Step 6: Then build the other docker containers

docker-compose -p kusama -f docker-compose.kusama-quick.yml up --build

Full deployment

The following steps will run a full Polkascan-stack that harvests blocks from a new local network.

Step 1: Clone repository:

git clone https://github.com/polkascan/polkascan-os.git

Step 2: Change directory:

cd polkascan-os

Step 3: Check available releases:

git tag

Step 4: Checkout latest releases:

git checkout v0.x.x

Step 5: Make sure to also clone submodules within the cloned directory:

git submodule update --init --recursive

Step 6: During the first run let MySQL initialize (wait for about a minute)

docker-compose -p kusama -f docker-compose.kusama-full.yml up -d mysql

Step 7: Then build the other docker containers

docker-compose -p kusama -f docker-compose.kusama-full.yml up --build

Other networks

• Polkadot CC1: Use docker-compose.polkadot-cc1-quick.yml and docker-compose.polkadot-cc1-full.yml
• Substrate Node Template (https://github.com/substrate-developer-hub/substrate-node-template): Use docker-compose.substrate-node-template.yml

Add custom types for Substrate Node Template

• Modify harvester/app/type_registry/substrate-node-template.json to match the introduced types of the custom chain
• Truncate runtime and runtime_* tables on database
• Start harvester
• Check http://127.0.0.1:8080/node-template/runtime-type if all type are now correctly supported
• Monitor http://127.0.0.1:8080/node-template/harvester/admin if blocks are being processed and try to restart by pressing "Process blocks in harvester queue" if process is interupted.
