Example of configuration

local-values.yaml:

extraConfigs:
  DD_SESSION_COOKIE_SECURE: 'True'
  DD_CSRF_COOKIE_SECURE: 'True'
  DD_SECURE_SSL_REDIRECT: 'True'
  DD_SOCIAL_AUTH_KEYCLOAK_OAUTH2_ENABLED: 'True'
  DD_SOCIAL_AUTH_KEYCLOAK_LOGIN_BUTTON_TEXT: "Войти через Keycloak" # <--- issue here
  DD_SOCIAL_AUTH_KEYCLOAK_PUBLIC_KEY: ""
  DD_SOCIAL_AUTH_KEYCLOAK_KEY: ""
  DD_SOCIAL_AUTH_KEYCLOAK_SECRET: ""
  DD_SOCIAL_AUTH_KEYCLOAK_AUTHORIZATION_URL: https://auth.example.org/auth/realms/users_auth/protocol/openid-connect/auth
  DD_SOCIAL_AUTH_KEYCLOAK_ACCESS_TOKEN_URL: https://auth.example.org/auth/realms/users_auth/protocol/openid-connect/token

Workaround is to replace cyrillic characters with latin ones

extraConfigs:
  ...
  DD_SOCIAL_AUTH_KEYCLOAK_LOGIN_BUTTON_TEXT: "Login with Keycloak"

According to Claude Code the above means that PYTHONUTF8=1 is needed as en env var in the container/pod.. But this should normally be automatically set since Python 3.7. Can you check what the value is in your pod and/or try setting it:

Diagnose: kubectl exec <pod> -- python -c "import sys; print(sys.getfilesystemencoding())"

Fix without rebuilding:

  extraConfigs:
    PYTHONUTF8: '1'

or

extraConfigs:
  LANG: 'C.UTF-8'
  LC_ALL: 'C.UTF-8'
