Add a new startup option to exit the exporter when an error occurs when connecting to the fail2ban socket file.
This option is set to "false" by default.
Rewrite the project README file to be more succinct and to the point. Add
new section on getting started quickly with either docker or the standalone
binary file.
Update CHANGELOG file with recent changes.
Add a basic systemd service file to serve as an example on how to run the
exporter as a system service. Add short README with an overview of the
service file.
Update the goreleaser config to rename the output binary and archive names
to `fail2ban_exporter` instead of defaulting to the project name. This
better aligns with conventions used by other exporters.
Update Dockerfile and Makefile to follow the new naming scheme.
Update the output archives to wrap the build files in a folder. This makes
extracting the archives a little easier.
BREAKING CHANGE: Release binary name has been changed to `fail2ban_exporter`.
Add a new method to the application startup to listen for OS shutdown
signals and handle them appropriately. A shutdown signal will cause the
app to exit immediately.
Use correct syntax for the `ENTRYPOINT` field in the Dockerfile to ensure
that OS signals get passed down to the running application.
Replace existing CLI flags to make them more consistent and follow a more
standard format.
Remove CLI flags and environment variables that are no longer relevant.
Add short `-v` option for version flag.
Update README with new documentation.
BREAKING CHANGE: Replace `--socket` flag with `--collector.f2b.socket`.
BREAKING CHANGE: Merge `--port` flag and `--web.listen-address` into a single flag.
BREAKING CHANGE: Remove `--collector.textfile` flag, its value is now derived from `--collector.textfile.directory`.
BREAKING CHANGE: Remove `F2B_COLLECTOR_TEXT` and `F2B_WEB_PORT` environment variables.
Update the docker image to remove the `run.sh` script and instead run the
exporter directly. This keeps the docker image as simple as possible.
Update README file with extra info on how to collect textfile metrics in
a docker container.
BREAKING CHANGE: Using the textfile collector in docker now requires setting environment variables.
Update the exporter logging on startup to include the exporter version,
the path to the fail2ban socket, and whether basic-auth is enabled or not.
Fix code printing error messages on invalid CLI parameters to correct line
breaks and correctly print the "usage" information.
Update the CLI param parser to include a default value for the fail2ban
socket file path. This is the default location fail2ban creates the socket
file on an ubuntu-based system.
Update the Dockerfile entrypoint script to use the correct version flag
syntax. The flag now requires two dashes instead of one. The syntax for
the texfile collector has also change, and the script was updated
accordingly.
Fix incorrect order of variable assignment when parsing CLI flags.
Replace CLI parsing functionality with the `kingpin` library to better
support configuring the tool with environment variables.
Add new environment variables to configure the tool.
BREAKING CHANGE: CLI params now require two dashes instead of one (e.g. `--socket`)
Add new CLI parameters to enable protecting the API endpoints with basic
auth authentication.
Wrap the server endpoints in a new auth middleware that protects it using
the provided basic auth credentials (if set).
Store the provided basic auth credentials as hashed values to prevent them
from being accidentally leaked.
Add unit tests to ensure the new functionality works as expected.
Update the sample Grafana dashboard to use a variable for the data
source. All panels have been updated to use the new variable. This makes
it easier to import the dashboard and have it work with different data
sources.
