## Docker
There is a supplied docker image to make deploying a server as a container easier.
```sh
docker run -d -v "$USER/.config/atuin:/config" ghcr.io/ellie/atuin:latest server start
```
## Docker Compose
Using the already build docker image hosting your own Atuin can be done using the supplied docker-compose file.
Create a `.env` file next to `docker-compose.yml` with contents like this:
```
ATUIN_DB_USERNAME=atuin
# Choose your own secure password
ATUIN_DB_PASSWORD=really-insecure
```
Create a `docker-compose.yml`:
```yaml
version: '3.5'
services:
atuin:
restart: always
image: ghcr.io/ellie/atuin:main
command: server start
volumes:
- "./config:/config"
links:
- postgresql:db
ports:
- 8888:8888
environment:
ATUIN_HOST: "0.0.0.0"
ATUIN_OPEN_REGISTRATION: "true"
ATUIN_DB_URI: postgres://$ATUIN_DB_USERNAME:$ATUIN_DB_PASSWORD@db/atuin
postgresql:
image: postgres:14
restart: unless-stopped
volumes: # Don't remove permanent storage for index database files!
- "./database:/var/lib/postgresql/data/"
environment:
POSTGRES_USER: $ATUIN_DB_USERNAME
POSTGRES_PASSWORD: $ATUIN_DB_PASSWORD
POSTGRES_DB: atuin
```
Start the services using `docker-compose`:
```sh
docker-compose up -d
```
### Using systemd to manage your atuin server
The following `systemd` unit file to manage your `docker-compose` managed service:
```
[Unit]
Description=Docker Compose Atuin Service
Requires=docker.service
After=docker.service
[Service]
# Where the docker-compose file is located
WorkingDirectory=/srv/atuin-server
ExecStart=/usr/bin/docker-compose up
ExecStop=/usr/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitBurst=3
[Install]
WantedBy=multi-user.target
```
Start and enable the service with:
```sh
systemctl enable --now atuin
```
Check if its running with:
```sh
systemctl status atuin
```

## Kubernetes
You could host your own Atuin server using the Kubernetes platform.
Create a [`secrets.yaml`](../k8s/secrets.yaml) file for the database credentials:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: atuin-secrets
type: Opaque
stringData:
ATUIN_DB_USERNAME: atuin
ATUIN_DB_PASSWORD: seriously-insecure
ATUIN_HOST: "127.0.0.1"
ATUIN_PORT: "8888"
ATUIN_OPEN_REGISTRATION: "true"
ATUIN_DB_URI: "postgres://atuin:seriously-insecure@localhost/atuin"
immutable: true
```
Create a [`atuin.yaml`](../k8s/atuin.yaml) file for the Atuin server:
```yaml

Finally, you may want to use a separate namespace for atuin, by creating a [`namespace.yaml`](../k8s/namespaces.yaml) file:
```yaml
```yaml
apiVersion: v1
kind: Namespace
metadata:
name: atuin-namespace
labels:
name: atuin
```
Note that this configuration will store the database folder _outside_ the kubernetes cluster, in the folder `/Users/firstname.lastname/.kube/database` of the host system by configuring the `storageClassName` to be `manual`. In a real enterprise setup, you would probably want to store the database content permanently in the cluster, and not in the host system.
You should also change the password string in `ATUIN_DB_PASSWORD` and `ATUIN_DB_URI` in the`secrets.yaml` file to a more secure one.
The atuin service on the port `30530` of the host system. That is configured by the `nodePort` property. Kubernetes has a strict rule that you are not allowed to expose a port numbered lower than 30000. To make the clients work, you can simply set the port in in your `config.toml` file, e.g. `sync_address = "http://192.168.1.10:30530"`.
Deploy the Atuin server using `kubectl`:
```shell
kubectl apply -f ./namespaces.yaml
kubectl apply -n atuin-namespace \
-f ./secrets.yaml \
-f ./atuin.yaml
```
The sample files above are also in the [k8s](../k8s) folder of the atuin repository.

## Docker
## Container deployment instructions
There is a supplied docker image to make deploying a server as a container easier.
```sh
docker run -d -v "$USER/.config/atuin:/config" ghcr.io/ellie/atuin:latest server start
```
## Docker Compose
Using the already build docker image hosting your own Atuin can be done using the supplied docker-compose file.
Create a `.env` file next to `docker-compose.yml` with contents like this:
```
ATUIN_DB_USERNAME=atuin
# Choose your own secure password
ATUIN_DB_PASSWORD=really-insecure
```
Create a `docker-compose.yml`:
```yaml
version: '3.5'
services:
atuin:
restart: always
image: ghcr.io/ellie/atuin:main
command: server start
volumes:
- "./config:/config"
links:
- postgresql:db
ports:
- 8888:8888
environment:
ATUIN_HOST: "0.0.0.0"
ATUIN_OPEN_REGISTRATION: "true"
ATUIN_DB_URI: postgres://$ATUIN_DB_USERNAME:$ATUIN_DB_PASSWORD@db/atuin
postgresql:
image: postgres:14
restart: unless-stopped
volumes: # Don't remove permanent storage for index database files!
- "./database:/var/lib/postgresql/data/"
environment:
POSTGRES_USER: $ATUIN_DB_USERNAME
POSTGRES_PASSWORD: $ATUIN_DB_PASSWORD
POSTGRES_DB: atuin
```
Start the services using `docker-compose`:
```sh
docker-compose up -d
```
### Using systemd to manage your atuin server
The following `systemd` unit file to manage your `docker-compose` managed service:
```
[Unit]
Description=Docker Compose Atuin Service
Requires=docker.service
After=docker.service
[Service]
# Where the docker-compose file is located
WorkingDirectory=/srv/atuin-server
ExecStart=/usr/bin/docker-compose up
ExecStop=/usr/bin/docker-compose down
TimeoutStartSec=0
Restart=on-failure
StartLimitBurst=3
[Install]
WantedBy=multi-user.target
```
Start and enable the service with:
```sh
systemctl enable --now atuin
```
Check if its running with:
```sh
systemctl status atuin
```
You can deploy you own atuin server in a container:
* See [docker](docker.md) for a sample docker configuration.
* See [k8s](k8s.md) for a sample kubernetes configuration.
