The Cardano Operations Book

Environment: Pre-Production Testnet

Usage: Testing release candidates and mainnet releases. Forks at approximately same time as mainnet (within an epoch of each other).

Long running. Since this parallels mainnet, if a bug occurs here, it needs fixed properly and can not be respun.

Upgrade Strategy:

• Release Candidates - 1/3 of nodes
• Official Releases - 2/3 of nodes
• Hard forks - all nodes
• Community requested to only deploy release candidates and official releases

Changes Requested by: Release Squad Lead

Approvals Required: SRE Tribe Lead, Cardano Head of Engineering, Cardano Head of Architecture, CF Representative

Responsible: IOG SRE

Accountable: Head of SRE/Release Squad Lead

Consulted: SPOs, IOG Tribes

Informed: Cardano Core Tribe, COO, Director of Engineering, VP Community

Configuration files

Compatible with cardano-node release 10.3.1

NOTE:
The non-block-producer node config has `PeerSharing` enabled by
default, so should not be used with block-producers.

Additionally, avoid connecting a block-producer not using p2p to a p2p
PeerSharing enabled relay as the block-producer's IP will be leaked.

• Node Config (Non-block-producers -- see note above)
• Node Config (Block-producers)
• DB Sync Config
• Submit API Config
• Node Topology
• Node Topology (Genesis mode)
• Peer Snapshot
• Byron Genesis
• Shelley Genesis
• Alonzo Genesis
• Conway Genesis
• Compiled guardrails script

Ouroboros Genesis Mode

For those preferring to use Genesis mode over bootstrap peers, the Genesis mode topology file given above can be used in place of the default topology file. The following requirements will also need to be met:

• The node config file will need to have ConsensusMode set to GenesisMode

• The peer snapshot file, provided above, will need to exist at the path declared at peerSnapshotFile in the genesis mode topology file: an absolute path, or a relative path with respect to the node binary directory

Guardrails reference script UTxO

For convenience, the guardrails script has been put on a UTxO so that it can be used as reference script in Treasury Withdrawal and Update Protocol Parameter proposals.
