Updating Your Node

It is very important, both for network security and for performance of your own node, to keep your node up-to-date with the latest version of the Pocket software. The following steps will show you how to update your node.

Release-specific changes

Each release may have specific modifications you need to make. This is just a general guideline for the steps you’ll typically take to update your node. Check the release notes for release-specific details.

Shutdown Pocket Core

Stop your Pocket Core instance running by submitting the shutdown command.

pocket stop
Warning

Once you shutdown Pocket Core, you will have 4 blocks (60 minutes) to complete the update and start Pocket Core again before your node gets jailed for downtime.

Backup blockchain data

Backing up your blockchain data will ensure a faster resync when you restart your node.

Navigate inside your $HOME/.pocket/ dir and save data/ (the entire directory):

cp -r ~/.pocket/data ~/backup/data

In the event of a corrupted database you can delete the bad data rm -r ~/.pocket/data and replace it with your backup cp -r ~/backup/data ~/.pocket/data.

Info

If you don’t have a backup, a temporary backup datadir may be provided alongside a release.

Ensure the latest Go version

Check your golang version. The release notes will specify which version it should be.

go version

If you need to update Go, use this guide.

Alternatively, if you use g, you can just run

sudo apt-get update
g install <version number>

Checkout latest Pocket Core

Source

Navigate into pocket-core directory

cd ~/go/src/github.com/pokt-network/pocket-core

Check out the latest release:

git pull
git checkout tags/RC-0.9.2

Rebuild the binary:

go build -o $GOPATH/bin/pocket ./app/cmd/pocket_core/main.go

Homebrew

Pull the latest tap:

brew upgrade pokt-network/pocket-core/pocket

Docker

Pull the latest container image:

docker pull poktnetwork/pocket-core:RC-0.9.2
docker pull poktnetwork/pocket:RC-0.9.2

Update config.json

Run the update-configs command, which creates a new config file ($HOME/.pocket/config/config.json) and backs up the old config file ($HOME/.pocket/config/config.json.bk).

pocket util update-configs

You’ll need to manually compare your backup file with the new file to copy over your personal config details.

Start Pocket

Start pocket running again.

pocket start

You can then test your node.
