# hatecomputers.club infra
A collection of playbooks to deploy the hatecomputers.club infra
## Prerequisites
- `ansible`
- `yamllint`
- `ansible-lint`
- an ssh key accepted on the root of each host in the `inventory`
## Setup
### Vault
Secrets are managed via `ansible-vault`. Initialize or update your vault
with new secrets via our custom `./ansible-vault-init.sh` script.
Additionally if you want to only update a single secret, use
`./ansible-vault-init.sh <secret_name>`.
If you don't want to be prompted to enter your password every time you
deploy something, put your password as plain text into `secrets.pwd` as
a single line in the root src directory:
```bash
echo "<your_password>" > secrets.pwd
```
Then you can add `--vault-password-file secrets.pwd` each time you run a
deployment (or you know, use `pass` or something if you're paranoid).
### Pre-commit hooks
1. clone the repo
```bash
git clone git@git.hatecomputers.club:hatecomputers.club/infra
cd infra
```
2. add a pre-commit hook
```bash
cd .git/hooks
touch pre-commit
```
3. insert into `pre-commit` the following contents:
```bash
#!/bin/sh
set -e
# lint yaml files
echo "running yamllint..."
yamllint --strict .
# follow ansible best-practices
echo "running ansible-lint"
ansible-lint
```
4. make it executable
```bash
chmod +x pre-commit
```
## Running
`ansible-playbook -e @secrets.enc deploy.yml` will run each respectively added playbook in `deploy.yml`
using the vault intialized in the previous steps.
Though in development, one should be testing individual playbooks, and `deploy.yml`
should be left for an idea of general order of things, or for a
full deployment after testing.
NOTE: It is highly advised to run `ansible-playbook` in an `ssh-agent` session to avoid retyping your password over and over. Something along the lines of:
```bash
ssh-agent $(echo $SHELL)
ssh-add ~/.ssh/<private-key>
```

#
# WARNING: heavily refactored in 0.9.0 release. Please review and
# customize settings for your setup.
#
# Changes: in most of the cases you should not modify this
# file, but provide customizations in jail.local file,
# or separate .conf files under jail.d/ directory, e.g.:
#
# HOW TO ACTIVATE JAILS:
#
# YOU SHOULD NOT MODIFY THIS FILE.
#
# It will probably be overwritten or improved in a distribution update.
#
# Provide customizations in a jail.local file or a jail.d/customisation.local.
# For example to change the default bantime for all jails and to enable the
# ssh-iptables jail the following (uncommented) would appear in the .local file.
# See man 5 jail.conf for details.
#
# [DEFAULT]
# bantime = 1h
#
#
# See jail.conf(5) man page for more information
# Comments: use '#' for comment lines and ';' (following a space) for inline comments
[INCLUDES]
#before = paths-distro.conf
before = paths-debian.conf
# The DEFAULT allows a global definition of the options. They can be overridden
# in each jail afterwards.
[DEFAULT]
#
# MISCELLANEOUS OPTIONS
#
# "bantime.increment" allows to use database for searching of previously banned ip's to increase a
# default ban time using special formula, default it is banTime * 1, 2, 4, 8, 16, 32...
#bantime.increment = true
# "bantime.rndtime" is the max number of seconds using for mixing with random time
# to prevent "clever" botnets calculate exact time IP can be unbanned again:
#bantime.rndtime =
# "bantime.maxtime" is the max number of seconds using the ban time can reach (doesn't grow further)
#bantime.maxtime =
# "bantime.factor" is a coefficient to calculate exponent growing of the formula or common multiplier,
# default value of factor is 1 and with default value of formula, the ban time
# grows by 1, 2, 4, 8, 16 ...
#bantime.factor = 1
# "bantime.formula" used by default to calculate next value of ban time, default value below,
# the same ban time growing will be reached by multipliers 1, 2, 4, 8, 16, 32...
#bantime.formula = ban.Time * (1<<(ban.Count if ban.Count<20 else 20)) * banFactor
#
# more aggressive example of formula has the same values only for factor "2.0 / 2.885385" :
#bantime.formula = ban.Time * math.exp(float(ban.Count+1)*banFactor)/math.exp(1*banFactor)
# "bantime.multipliers" used to calculate next value of ban time instead of formula, corresponding
# previously ban count and given "bantime.factor" (for multipliers default is 1);
# following example grows ban time by 1, 2, 4, 8, 16 ... and if last ban count greater as multipliers count,
# always used last multiplier (64 in example), for factor '1' and original ban time 600 - 10.6 hours
#bantime.multipliers = 1 2 4 8 16 32 64
# following example can be used for small initial ban time (bantime=60) - it grows more aggressive at begin,
# for bantime=60 the multipliers are minutes and equal: 1 min, 5 min, 30 min, 1 hour, 5 hour, 12 hour, 1 day, 2 day
#bantime.multipliers = 1 5 30 60 300 720 1440 2880
# "bantime.overalljails" (if true) specifies the search of IP in the database will be executed
# cross over all jails, if false (default), only current jail of the ban IP will be searched
#bantime.overalljails = false
# --------------------
# "ignoreself" specifies whether the local resp. own IP addresses should be ignored
# (default is true). Fail2ban will not ban a host which matches such addresses.
#ignoreself = true

# can be defined using space (and/or comma) separator.

# "backend" specifies the backend used to get files modification.
# Available options are "pyinotify", "gamin", "polling", "systemd" and "auto".
# This option can be overridden in each jail as well.
#
# pyinotify: requires pyinotify (a file alteration monitor) to be installed.
# If pyinotify is not installed, Fail2ban will use auto.
# gamin: requires Gamin (a file alteration monitor) to be installed.
# If Gamin is not installed, Fail2ban will use auto.
# polling: uses a polling algorithm which does not require external libraries.
# systemd: uses systemd python library to access the systemd journal.
# Specifying "logpath" is not valid for this backend.
# See "journalmatch" in the jails associated filter config
# auto: will try to use the following backends, in order:
# pyinotify, gamin, polling.
#
# Note: if systemd backend is chosen as the default but you enable a jail
# for which logs are present only in its own log files, specify some other
# backend for that jail (e.g. polling) and provide empty value for
# journalmatch. See https://github.com/fail2ban/fail2ban/issues/959#issuecomment-74901200
backend = systemd
# "usedns" specifies if jails should trust hostnames in logs,
# warn when DNS lookups are performed, or ignore all hostnames in logs
#
# yes: if a hostname is encountered, a DNS lookup will be performed.
# warn: if a hostname is encountered, a DNS lookup will be performed,
# but it will be logged as a warning.
# no: if a hostname is encountered, will not be used for banning,
# but it will be logged as info.
# raw: use raw value (no hostname), allow use it for no-host filters/actions (example user)

# "logencoding" specifies the encoding of the log files handled by the jail
# This is used to decode the lines from the log file.
# Typical examples: "ascii", "utf-8"

# auto: will use the system locale setting

# "enabled" enables the jails.
