Demonstrate a simple spire setup in a local docker-compose environment.

Brief

• This example bootstraps a spire server and agent in a local docker-compose environment.
• The spire agent joins the server by x509pop node attestation.
• The key target in the Makefile generates self-signed certificates and private keys for both x509 pop node attestation and server upstream authority.

Usage

• Run make up to start the docker-compose. It will execute the key target to generate new keys and certificates.
• Run scripts/create-entries.sh to register workload entries
• Run scripts/agent-test.sh to fetch X.509 and JWT SVID.
