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.
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 new metrics around basic jail configuration. The new metrics expose the
max retries, ban time, and find time for each jail.
Update project README with the new metrics.
Create a new `collector` folder to store the code for the different
collectors. Move the existing f2b and textfile collectors to this folder.
Minor refactors to the f2b collector to better match the code style of the
newer textfile collector.
Update the goreleaser config to remove windows builds. It doesn't make
sense to build binaries for windows because fail2ban does not provide any
binary for windows. If windows support is required, docker can be used.
