Oxidized is a network device configuration backup tool. It's a RANCID replacement!

It is light and extensible and supports over 130 operating system types.

Feature highlights:

* Automatically adds/removes threads to meet configured retrieval interval
* Restful API to a move node immediately to head-of-queue (GET/POST /node/next/[NODE])
* Syslog udp+file example to catch config change events (IOS/JunOS) and trigger a config fetch
  * Will signal which IOS/JunOS user made the change, can then be used by output modules (via POST)
  * The `git` output module uses this info - 'git blame' will show who changed each line
* Restful API to reload list of nodes (GET /reload)
* Restful API to fetch configurations (/node/fetch/[NODE] or /node/fetch/group/[NODE])
* Restful API to show list of nodes (GET /nodes)
* Restful API to show list of version for a node (/node/version[NODE]) and diffs

## Installation

### Debian and Ubuntu

Debian "buster" or newer and Ubuntu 17.10 (artful) or newer are recommended. On Ubuntu, begin by enabling the `universe`
repository (required for libssh2-1-dev):

```shell
add-apt-repository universe
```

Install the dependencies:

```shell
apt-get install ruby ruby-dev libsqlite3-dev libssl-dev pkg-config cmake libssh2-1-dev libicu-dev zlib1g-dev g++ libyaml-dev
```

Finally, install the gems:

```shell
gem install oxidized
gem install oxidized-script oxidized-web # If you don't install oxidized-web, ensure "rest" is removed from your Oxidized config.
```

### CentOS, Oracle Linux, Red Hat Linux

On CentOS 6 and 7 / RHEL 6 and 7, begin by installing Ruby 2.3 or greater. This can be accomplished in one of several ways:

Install Ruby 2.3 from [SCL](https://www.softwarecollections.org/en/scls/rhscl/rh-ruby23/):

```shell
yum install centos-release-scl
yum install rh-ruby30 rh-ruby30-ruby-devel
scl enable rh-ruby30 bash
```

The following additional packages will be required to build the dependencies:

```shell
yum install make cmake which sqlite-devel openssl-devel libssh2-devel ruby gcc ruby-devel libicu-devel gcc-c++
```

Alternatively, install Ruby 2.6 via RVM by following the instructions:

Make sure you dont have any leftover ruby:
```yum erase ruby```

Then, install gpg key and rvm

```shell
sudo gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB
curl -sSL https://get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm requirements run
rvm install 3.0
rvm use 3.0
```

Install oxidized requirements:
```yum install make cmake which sqlite-devel openssl-devel libssh2-devel gcc libicu-devel gcc-c++```

Install the gems:
```gem install oxidized oxidized-web```

You need to wrap the gem and reference the wrap in the systemctl service file:
```rvm wrapper oxidized```

You can see where the wrapped gem is via
```rvm wrapper show oxidized```
Use that path in the oxidized.service file, restart the systemctl daemon, run oxidized by hand once, edit config file, start service.

### FreeBSD

[Use RVM to install Ruby v2.3](#installing-ruby-23-using-rvm), then install all required packages and gems:

```shell
pkg install cmake pkgconf
gem install oxidized
gem install oxidized-script oxidized-web
```

Oxidized is also available via [FreeBSD ports](https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203374):

```shell
pkg install rubygem-oxidized rubygem-oxidized-script rubygem-oxidized-web
```

### Build from Git

```shell
git clone https://github.com/ytti/oxidized.git
cd oxidized/
gem install bundler
rake install
```

### Running with Docker

Currently, Docker Hub automatically builds the master branch for linux/amd64 and linux/arm64 platforms as [oxidized/oxidized](https://hub.docker.com/r/oxidized/oxidized/), you can make use of this container or build your own.

To build your own, clone git repo:

```shell
git clone https://github.com/ytti/oxidized
```

Then, build the container locally (requires docker 17.05.0-ce or higher):

```shell
docker build -q -t oxidized/oxidized:latest oxidized/
```

Once you've built the container (or chosen to make use of the automatically built container in Docker Hub, which will be downloaded for you by docker on the first `run` command had you not built it), proceed as follows:

Create a configuration directory in the host system:

```shell
mkdir /etc/oxidized
```

Run the container for the first time to initialize the config:

_Note: this step in only required for creating the Oxidized configuration file and can be skipped if you already have one._

```shell
docker run --rm -v /etc/oxidized:/home/oxidized/.config/oxidized -p 8888:8888/tcp --user oxidized -t oxidized/oxidized:latest oxidized
```

If the RESTful API and Web Interface are enabled, on the docker host running the container
edit `/etc/oxidized/config` and modify `rest: 127.0.0.1:8888` to `rest: 0.0.0.0:8888`. This will bind port 8888 to all interfaces, and expose the port so that it could be accessed externally. [(Issue #445)](https://github.com/ytti/oxidized/issues/445)

Alternatively, you can use docker-compose to launch the oxidized container:

```yaml
# docker-compose.yml
# docker-compose file example for oxidized that will start along with docker daemon
---
version: "3"
services:
  oxidized:
    restart: always
    image: oxidized/oxidized:latest
    ports:
      - 8888:8888/tcp
    environment:
      CONFIG_RELOAD_INTERVAL: 600
    volumes:
       - config:/home/oxidized/.config/oxidized/
volumes:
  config:
```

Create the `/etc/oxidized/router.db` (see [CSV Source](docs/Sources.md#source-csv) for further info):

```shell
vim /etc/oxidized/router.db
```

Run container again to start oxidized with your configuration:

```shell
docker run -v /etc/oxidized:/home/oxidized/.config/oxidized -p 8888:8888/tcp -t oxidized/oxidized:latest
oxidized[1]: Oxidized starting, running as pid 1
oxidized[1]: Loaded 1 nodes
Puma 2.13.4 starting...
* Min threads: 0, max threads: 16
* Environment: development
* Listening on tcp://0.0.0.0:8888
```

If you want to have the config automatically reloaded (e.g. when using a http source that changes):

```shell
docker run -v /etc/oxidized:/home/oxidized/.config/oxidized -p 8888:8888/tcp -e CONFIG_RELOAD_INTERVAL=3600 -t oxidized/oxidized:latest
```

If you need to use an internal CA (e.g. to connect to an private github instance):

```shell
docker run -v /etc/oxidized:/home/oxidized/.config/oxidized -v /path/to/MY-CA.crt:/usr/local/share/ca-certificates/MY-CA.crt -p 8888:8888/tcp -e UPDATE_CA_CERTIFICATES=true -t oxidized/oxidized:latest
```

### Running with podman-compose
Under [examples/podman-compose](examples/podman-compose), you will find a complete
example of how to integrate the container into a docker-compose.yml file.

### Installing Ruby 2.3 using RVM

Install Ruby 2.3 build dependencies

```shell
yum install curl gcc-c++ patch readline readline-devel zlib zlib-devel
yum install libyaml-devel libffi-devel openssl-devel make cmake
yum install bzip2 autoconf automake libtool bison iconv-devel libssh2-devel libicu-devel
```

Install RVM

```shell
curl -L get.rvm.io | bash -s stable
```

Setup RVM environment and compile and install Ruby 2.3 and set it as default

```shell
source /etc/profile.d/rvm.sh
rvm install 2.3
rvm use --default 2.3
```

## Configuration

Oxidized configuration is in YAML format. Configuration files are subsequently sourced from `/etc/oxidized/config` then `~/.config/oxidized/config`. The hashes will be merged, this might be useful for storing source information in a system wide file and  user specific configuration in the home directory (to only include a staff specific username and password). Eg. if many users are using `oxs`, see [Oxidized::Script](https://github.com/ytti/oxidized-script).

It is recommended practice to run Oxidized using its own username.  This username can be added using standard command-line tools:

```shell
useradd -s /bin/bash -m oxidized
```

> It is recommended __not__ to run Oxidized as root.

To initialize a default configuration in your home directory `~/.config/oxidized/config`, simply run `oxidized` once. If you don't further configure anything from the output and source sections, it'll extend the examples on a subsequent `oxidized` execution. This is useful to see what options for a specific source or output backend are available.

You can set the env variable `OXIDIZED_HOME` to change its home directory.

```shell
OXIDIZED_HOME=/etc/oxidized

$ tree -L 1 /etc/oxidized
/etc/oxidized/
├── config
├── log-router-ssh
├── log-router-telnet
├── pid
├── router.db
└── repository.git
```

## Source

Oxidized supports [CSV](docs/Configuration.md#source-csv),  [SQLite](docs/Configuration.md#source-sqlite), [MySQL](docs/Configuration.md#source-mysql) and [HTTP](docs/Configuration.md#source-http) as source backends. The CSV backend reads nodes from a rancid compatible router.db file. The SQLite and MySQL backends will fire queries against a database and map certain fields to model items. The HTTP backend will fire queries against a http/https url. Take a look at the [Configuration](docs/Configuration.md) for more details.

## Outputs

Possible outputs are either [File](docs/Configuration.md#output-file), [GIT](docs/Configuration.md#output-git), [GIT-Crypt](docs/Configuration.md#output-git-crypt) and [HTTP](docs/Configuration.md#output-http). The file backend takes a destination directory as argument and will keep a file per device, with most recent running version of a device. The GIT backend (recommended) will initialize an empty GIT repository in the specified path and create a new commit on every configuration change. The GIT-Crypt backend will also initialize a GIT repository but every configuration push to it will be encrypted on the fly by using `git-crypt` tool. Take a look at the [Configuration](docs/Configuration.md) for more details.

Maps define how to map a model's fields to model [model fields](https://github.com/ytti/oxidized/tree/master/lib/oxidized/model). Most of the settings should be self explanatory, log is ignored if `use_syslog` is set to `true`.

First create the directory where the CSV `output` is going to store device configs and start Oxidized once.

```shell
mkdir -p ~/.config/oxidized/configs
oxidized
```

Now tell Oxidized where it finds a list of network devices to backup configuration from. You can either use CSV or SQLite as source. To create a CSV source add the following snippet:

```yaml
source:
  default: csv
  csv:
    file: ~/.config/oxidized/router.db
    delimiter: !ruby/regexp /:/
    map:
      name: 0
      model: 1
```

Now lets create a file based device database (you might want to switch to SQLite later on). Put your routers in `~/.config/oxidized/router.db` (file format is compatible with rancid). Simply add an item per line:

```text
router01.example.com:ios
switch01.example.com:procurve
router02.example.com:ios
```

Run `oxidized` again to take the first backups.

## Extra

### Ubuntu init setup

The systemd service assumes that you have a user named 'oxidized' and that oxidized is in one of the following paths:

```text
/sbin
/bin
/usr/sbin
/usr/bin
/usr/local/bin
```

1. Copy systemd service file from extra/ folder to /etc/systemd/system

```shell
sudo cp extra/oxidized.service /etc/systemd/system
```

2. Setup `/var/run/`

```shell
mkdir /run/oxidized
chown oxidized:oxidized /run/oxidized
```

3. Make oxidized start on boot

```shell
sudo systemctl enable oxidized.service
```

## Help Needed

As things stand right now, `oxidized` is maintained by very few people.
We would appreciate more individuals and companies getting involved in Oxidized.

Beyond software development, documentation or maintenance of Oxidized, you could
become a model maintainer, which can be done with little burden and would be a
big help to the community.
