#Redis

## Deploying the Redis.
To deploy Redis, you will need to complete the following steps:

### 1. Create an application with a suitable tariff.
```{eval-rst}
.. admonition:: Attention
   :class: attention

   Stable work is possible at tariffs not lower than “Initial”.
```

### 2. At the “Downloading data” stage, select “Via Git”.
![db_create](../img/db_create.png)

### 3. At the "Configuration" stage, select "db" and "redis" and click "Finish".
![mongo](../img/mongo.png)

The deployment uses the Docker image `redis/redis-stack-server:${meta.toolchain.version}`. Parameter `meta.toolchain.version` 
optional. If not specified, the latest `redis/redis-stack-server:latest` image will be used.

Since the value of the `meta.toolchain.version` parameter is a redis image tag, you can use 
use a custom tag from [docker hub](https://hub.docker.com/r/redis/redis-stack-server/tags).

### 4. Specify the required environment parameters.

In the "Variables" section of the project, you must set the following [environment variables](../applications/configuration/variables.md):
* To add a `default` user password and store it securely, you need to click on the "Create Secret" button. 
In the "Name" field, enter `REDIS_ARGS`, and in the value field, enter `--requirepass <desired password>`.

```{eval-rst}
.. admonition:: Important
   :class: warning

   Come up with a sufficiently complex password for the database so that attackers cannot gain access to it.
```
If necessary, you can set other parameters supported by the image. You can learn more about these options on the [image page](https://hub.docker.com/r/redis/redis-stack-server).

### 5. On the "Configuration" page of the application, click the "Build" button.
If the configuration is empty, you must select “db” and “mongodb” again and click “apply”, and then “build”.

## Connect to the database
```{eval-rst}
.. admonition:: Attention
   :class: attention

   Connecting to the database is only possible from other projects created in Amverum.
```
To connect to the database, you must use the `6379` port and the internal domain name specified on the "Info" page in the format:

`amverum-<username>-run-<transliterated-project-name>`

## Deploying Redis Insight

The procedure is the same as deploying the DBMS itself:

### 1. Create an application with a suitable tariff.
```{eval-rst}
.. admonition:: Attention
   :class: attention

   For mongo-express to work, you need a container with a tariff of at least “Initial”.
```

### 2. At the “Data Upload” stage, select “Via Git”
![db_create](../img/db_create.png)

### 3. At the "Configuration" stage, select "db" and "redis-insight" and click "Finish"

Deployment uses [image](https://hub.docker.com/r/redislabs/redisinsight) Docker `redislabs/redisinsight:${meta.toolchain.version}`

### 4. Specify the required environment parameters.

In the "Variables" section of the project, you must set the following [environment variables](../applications/configuration/variables.md):
* Variable `RIAUTHPROMPT` = `true` 
* RITRUSTEDORIGINS - allowed hosts to access = `https://<transliterated-project-name>-<username>.amverum.io,http://localhost:8001`
* Variable RIAUTHTIMER set to 30
* RIPROXYENABLE variable set to `true`

### 5. On the "Configuration" page of the application, click the "Build" button
If the configuration is empty, you must select “db” and “redis-insight” again and click “apply”, and then “build”.

### 6. In the "Settings" section of the application, activate [free domain name](../applications/configuration/network.md#free-domain-name-amverum) or [add your own](../applications/configuration/network.md#your-domain-name).

```{eval-rst}
.. admonition:: Cunning
   :class: hint

   To save on consuming a project with mongo-express, we recommend pausing it after finishing work.
