kevinveenbirkenbachandClaude Opus 5 c7238adb0a fix(web-app-keycloak): absorb a rotated admin password instead of locking out
Keycloak stores the permanent admin's password in its own database. When the
inventory value rotates, the next deploy renders a credential that
authenticates against nothing, and the role cannot reach the instance it just
restarted. The bootstrap account is no way back either: Keycloak writes
KC_BOOTSTRAP_ADMIN_* once, on an empty database, and upstream states it is
meant to be removed once a permanent admin exists.

The role now keeps the credential its predecessor used. Before sys-stk-full
re-renders the environment file with force: true, utils/capture_previous_admin.yml
reads KEYCLOAK_PERMANENT_ADMIN_PASSWORD out of the copy still on disk. When the
login after the restart is refused, utils/converge_previous_admin.yml signs in
with that captured value and moves the account onto the newly rendered one,
which the restarted container already carries in its environment. The bootstrap
fallback stays what its name says: the path for an instance that has never been
deployed. A host with no previous file captures nothing and goes straight there.

Reading the file back needs the inverse of dotenv_quote, which did not exist.
dotenv_unquote switches on the same DEPLOYMENT_MODE as the forward direction, so
a value written in compose is unescaped and a value written in swarm is taken
verbatim; dotenv_value pulls one assignment's raw right-hand side out of the
rendered text. The password never reaches argv: the convergence login passes it
through container exec -e plus the task's environment:.

Custom Filter Plugins for Infinito.Nexus

This directory contains custom Ansible filter plugins used within the Infinito.Nexus project.

When to Use a Filter Plugin

  • Transform values: Use filters to transform, extract, reformat, or compute values from existing variables or facts.
  • Inline data manipulation: Filters are designed for inline use in Jinja2 expressions (in templates, tasks, vars, etc.).
  • No external lookups: Filters only operate on data you explicitly pass to them and cannot access external files, the Ansible inventory, or runtime context.

Examples

{{ role_name | entity_name }}
{{ my_list | unique }}
{{ user_email | regex_replace('^(.+)@.*$', '\\1') }}

When not to Use a Filter Plugin

  • If you need to load data from an external source (e.g., file, environment, API), use a lookup plugin instead.
  • If your logic requires access to inventory, facts, or host-level information that is not passed as a parameter.

Schema 🗺️

How csp_filters.py assembles one application's Content-Security-Policy. Scope is the header build, not the other filters in this directory.

Styles carry 'unsafe-inline' by default; scripts do not. The logout grant is the only path that puts it into a script directive.
