# Installation
After installation take a look at the [Post-install steps](#post-install-configuration).
Note: Any [PaaS](https://en.wikipedia.org/wiki/Platform_as_a_service) or [SaaS](https://en.wikipedia.org/wiki/Software_as_a_service) provider/software (Heroku, YunoHost, Repli...) are unsupported. Use them at your own risk. They **WILL** cause problems with Invidious and might even suspend your account for "abuse" since Invidious is heavy, bandwidth intensive and technically a proxy (and most providers don't like them). If you use one and want to report an issue, please mention which one you use.

## Hardware requirements
Running Invidious requires at least 20GB disk space, 512MB of free RAM (so ~2G installed on the system), as long as it is restarted regularly, as recommended in the post-install configuration. Public instances should ideally have at least 60G disk space, 4GB of RAM, 2vCPU, a 200 mbps link and 20TB of traffic (no data cap/unlimited traffic is preferred).
Compiling Invidious requires at least 2.5GB of free RAM (We recommend to have at least 4GB installed).
If you have less (e.g on a cheap VPS) you can setup a SWAP file or partition, so the combined amount is >= 4GB.
## Docker
2022-03-12 22:51:18 +00:00
**The Invidious docker image is only [available on Quay](https://quay.io/repository/invidious/invidious) because, unlike Docker Hub, [Quay is Free and Open Source Software](https://github.com/quay/quay/blob/master/LICENSE). This is reflected in the `docker-compose.yml` file used in this walk-through.**
Ensure [Docker Engine](https://docs.docker.com/engine/install) and [Docker Compose](https://docs.docker.com/compose/install) are installed before beginning.
### Docker-compose method (production)
**This method uses the pre-built Docker image from quay**
Note: Currently the repository has to be cloned, this is because the `init-invidious-db.sh` file and the `config/sql` directory have to be mounted to the postgres container (See the volumes section in the docker-compose file below). This "problem" will be solved in the future.
```bash
git clone https://github.com/iv-org/invidious.git
cd invidious
```
Edit the docker-compose.yml with this content:
```docker
version: "3"
services:
invidious:
image: quay.io/invidious/invidious:latest
# image: quay.io/invidious/invidious:latest-arm64 # ARM64/AArch64 devices

POSTGRES_USER: kemal
POSTGRES_PASSWORD: kemal
healthcheck:
test: ["CMD-SHELL", "pg_isready -U $$POSTGRES_USER -d $$POSTGRES_DB"]

```
Note: This compose is made for a true "production" setup, where Invidious is behind a reverse proxy. If you prefer to directly access Invidious, replace `127.0.0.1:3000:3000` with `3000:3000` under the `ports:` section.
### Docker-compose method (development)
**This method builds a Docker image from source**
```bash
git clone https://github.com/iv-org/invidious.git
cd invidious
docker-compose up
```

### Windows
Crystal, the programming language used by Invidious, [doesn't officially support Windows yet](https://github.com/crystal-lang/crystal/issues/5430) but you can still install Invidious:
- By installing [Docker desktop](https://docs.docker.com/desktop/install/windows-install/) and then following [our guide about Docker](#docker).
- By installing [Windows Subsystem for Linux](https://msdn.microsoft.com/en-us/commandline/wsl/about) and then following [our guide about Linux](#linux).
2023-12-03 23:49:25 +00:00
- By installing [Windows-specific builds](https://github.com/crystal-lang/crystal/releases/) of Crystal. Be wary, as we don't currently have records of Invidious being tested on those "unsupported" builds yet.
## Post-install configuration:
Detailed configuration available in the [configuration guide](./configuration.md).
2023-01-06 18:11:37 +00:00
You must set a random generated value for the parameter `hmac_key:`! On Linux you can generate it using the command `pwgen 20 1`.
Because of various issues Invidious **must** be restarted often, at least once a day, ideally every hour.
If you use a reverse proxy, you **must** configure invidious to properly serve request through it:
`https_only: true` : if you are serving your instance via https, set it to true
`domain: domain.ext`: if you are serving your instance via a domain name, set it here
`external_port: 443`: if you are serving your instance via https, set it to 443
2023-12-28 15:35:12 +00:00
`use_pubsub_feeds: true`: if you are serving your instance on the internet, allow for faster notification of new videos ([detailed explanation](https://github.com/iv-org/invidious/blob/97c4165f55c4574efb554c9dae8d919d08da1cdd/config/config.example.yml#L409)).
`use_innertube_for_captions: true`: if you are serving a public instance or you are hosting invidious in a datacenter, allow to unblock captions ([detailed explanation](https://github.com/iv-org/invidious/issues/2567#issuecomment-1727928996)).
