Add unit tests for the basicAuth to ensure it behaves as expected.
Update the basic auth provider struct in the cfg package to handle all the
hashing automatically.
Fix the circular dependency by adding a new BasicAuthProvider interface to
wrap the basic auth values.
Add unit tests for the hash functions.
Refactor functions to use the new basic auth provider interface.
Update how the basic auth credentials are stored in the application to use
a hashed value instead of the raw value. This prevents the raw value from
being accidentally leaked.
Add new `auth` package for functions related to authentication.
Add check to ensure basic auth username and password are both set or both
unset. It isn't valid to set one without the other.
Update README file to include the new CLI parameters.
Add new CLI parameters to enable protecting the API endpoints with basic
auth authentication.
Wrap the server endpoints in a new authMiddleware that protects it using
the provided basic auth credentials (if set).
Add new -web.listen-address command line parameter, so that the
listening interface can be limited. This follows a similar style as
the official prometheus-node-exporter project.
Update project README with the new parameter.
Remove all database-based metrics from the metrics endpoint.
Remove all code related to pulling metrics from the fail2ban database.
Remove all configuration variables related to the fail2ban database.
The CLI parameter for the database path was not removed to avoid breaking
compatibility.
Update docker entrypoint to remove references to the fail2ban database.
Remove all references to the old database metrics from the README.
Add support for collecting arbitrary metrics from a textfile as well as
metrics collected from fail2ban. This allows other data to be exported
along with the fail2ban metrics (e.g. instance metadata).
Update the docker image to allow mounting a folder with a collection of
metric files to be exported. Only files ending in `.prom` with be read.
Update project README with the new functionality.
Update all old database-based metrics to include the `deprecated` text.
Add a warning on startup if connecting to the fail2ban database to state
that this functionality will be removed in a future release.
Rename deprecated methods and variables.
Add support for connecting the exporter directly to the fail2ban server's
socket to send requests and receive data. The path to the socket file is
optional and specified on startup.
Export a new metric based on the response of the `ping` command sent to the
fail2ban server. The metric is set to 1 if the server responds with `pong`
and 0 in any other case. This metric is only shown if the path to the
socket file was provided on startup.
Update the project structure to move all golang files to a new `src/`
folder. This keeps all the code located in the same place and easier to
work with.
Update the Makefile and goreleaser config to continue to work with the new
folder structure.
