With version 17 of Keycloak, the Wildfly based distribution was
deprecated in favor of the one based on Quarkus. The difference in
configuration is massive and to accommodate it, both the package and
module had to be rewritten.
This fixes the following issues with the database provisioning script
included in the services.keycloak module:
- It lacked permission to access the DB password file specified in the
module option 'services.keycloak.database.passwordFile'.
- It prevented Keycloak from starting after the second time if the user
chose MySQL for the database.
Instead of referencing all library functions through `lib.` and
builtins through `builtins.` at every invocation, inherit them into
the appropriate scope.
Use systemd's LoadCredential mechanism to make the secret files
available to the service.
This gets rid of the privileged part of the ExecPreStart script which
only served to copy these files and assign the correct
permissions. There's been issues with this approach when used in
combination with DynamicUser, where sometimes the user isn't created
before the ExecPreStart script runs, causing the error
install: invalid user ‘keycloak’
This should fix that issue.
Unfortunately, all of the ExecPreStart script had to be moved to
ExecStart, since credentials aren't provided to ExecPreStart. See
https://github.com/systemd/systemd/issues/19604.
This together with extraConfig:
{
"subsystem=undertow"."server=default-server"."http-listener=default"."proxy-address-forwarding" = true;
"subsystem=undertow"."server=default-server"."https-listener=https"."proxy-address-forwarding" = true;
}
Allows to run Keycloak behind a reverse proxy that provides
X-Forwarded-* headers.
Allow update commands in the script to be ordered using `mkOrder`.
If we encounter ordered sub-objects we sort them by priority.
To implement this we now explicitly pass current node in `recurse`,
which also allows us to clean up edge case for top-level node.
Also refactor `recurse` to avoid passing result text argument; we
weren't tail recursive before anyway.
some options have default that are best described in prose, such as
defaults that depend on the system stateVersion, defaults that are
derivations specific to the surrounding context, or those where the
expression is much longer and harder to understand than a simple text
snippet.
Instead of requiring the user to bundle the certificate and private
key into a single file, provide separate options for them. This is
more in line with most other modules.
`install` copies the files before setting their mode, so there could
be a breif window where the secrets are readable by other users
without a strict umask.
Feeding `psql` the password on the command line leaks it through the
`psql` process' `/proc/<pid>/cmdline` file. Using `echo` to put the
command in a file and then feeding `psql` the file should work around
this, since `echo` is a bash builtin and thus shouldn't spawn a new
process.
Using `replace-literal` to insert secrets leaks the secrets through
the `replace-literal` process' `/proc/<pid>/cmdline`
file. `replace-secret` solves this by reading the secret straight from
the file instead, which also simplifies the code a bit.
This reverts commit d9e18f4e7f.
This change is broken, since it doesn't configure the proper database
username in keycloak when provisioning a local database with a custom
username. Its intended behavior is also potentially confusing and
dangerous, so rather than fixing it, let's revert to the old one.
