sys-ca-selfsigned

Description

Creates (once) a local Root CA (self-signed) for the Infinito.Nexus environment.

This role provisions:

  • Root CA private key: {{ CA_ROOT.key_host }}

  • Root CA certificate: {{ CA_ROOT.cert_host }}

The generated Root CA certificate can be injected into containers (e.g. via sys-svc-compose-ca) so that containers trust your internal TLS endpoints.

Overview

This role provisions a local Root CA (self-signed, CA:TRUE) for trusting internal TLS endpoints. Produces /etc/infinito.nexus/ca/root-ca.crt for sys-svc-compose-ca injection.

Cosmos

The diagram places sys-ca-selfsigned in the Infinito.Nexus cosmos: the components it deploys (capabilities), the central services it consumes (dependencies), and its outward reach (federation and bridged external networks).

Solid 1:1 edges are fixed relationships; dashed 0..1 edges are conditional (enabled only in matching deployments); red 0..0 edges are turned off in this role. Node markers show the role’s deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in meta/main.yml.

Features

  • Automated provisioning: Configured by Ansible without manual steps.

Outputs

  • CA_ROOT.cert_host (default: /etc/infinito.nexus/ca/root-ca.crt)

  • CA_ROOT.key_host (default: /etc/infinito.nexus/ca/root-ca.key)

Inputs

  • CA_ROOT (mapping)

    • base_dir (string): base directory for CA files

    • cert_host (string): host path to Root CA certificate

    • key_host (string): host path to Root CA private key

    • openssl_conf_host (string): host path for generated openssl.cnf

    • days (int): certificate validity

    • key_bits (int): RSA key size

    • subject (mapping): DN fields (C/O/OU/CN)

    • force_regen (bool): if true, remove and regenerate key/cert

Notes

  • The Root CA private key is generated unencrypted (automation-friendly). Protect file permissions.

  • This role does not sign leaf certificates. It only provisions the Root CA.
