Deploy bostrom node from snapshot

Download snapshot

First, go to Cyber Snapshot Robot page

Latest post will show you available snapsot:

Сlick on the link with the block and you will see two results:

We typicaly store only latest snashot, older might be available only in IPFS if someone stored them.

The first one is a hash of the current snapshot that can be downloaded directly from ipfs (to use this way, you need an ipfs client installed)

ipfs get <insert the hash here> --output bostrom_pruned.tar.gz

The second hash contains url that can be downloaded directly:

wget https://<link_from_above>

Unpack snapshot

Single thread:

tar -xvzf bostrom_pruned_<snap_block>.tar.gz

Multiple threads (much faster and require pigz installation):

apt install pigz  

tar -I pigz -xf bostrom_pruned_<snap_block>.tar.gz -C ./

Stop Cyber

docker stop bostrom

Remove old data from home directory

Dont forget to use correct path if your node is not in $HOME of your user.

rm -rf ~/.cyber/data ~/.cyber/wasm

Move unpacked folders into home directory

cd bostrom_pruned_<snap_block>  

mv data/ ~/.cyber/  

mv wasm/ ~/.cyber/

Set up your pruning strategy to everything

To save the space ont the disk consumed by the node set pruning to everything (lightest one) and set snapshot-interval to 0 in .cyber/config/app.toml:

pruning = "everything"  

snapshot-interval = 0

Start Cyber container and check logs

docker start bostrom  

docker logs bostrom -f --tail 10

You will see node started sync from the snapshot block.

When done dont forget to remove folder and archive to save some space

rm -rf bostrom_pruned_<snap_block> bostrom_pruned_<snap_block>.tar.gz
