Strapi gives you many possible deployment options for your project or application. Strapi can be deployed on traditional hosting servers or services such as Heroku, AWS, Azure and others. The following documentation covers how to develop locally with Strapi and deploy Strapi with various hosting options.
If you are passing a number of configuration item values via environment variables which is always encouraged for production environment to keep application stateless, checkout the section for [Dynamic Configuration](../configurations/configurations.md#dynamic-configurations). Here is a hint on how to do it for production, for the configuration mentioned above:
If you want to host the administration on another server than the API, [please take a look at this dedicated section](../advanced/customize-admin.md#deployment).
This is a step-by-step guide for deploying a Strapi project to [Digital Ocean](https://www.digitalocean.com/). Databases can be on a [Digital Ocean Droplet](https://www.digitalocean.com/docs/droplets/) or hosted externally as a service. Prior to starting this guide, you should have created a [Strapi project](/3.x.x/getting-started/quick-start.html).
Digital Ocean calls a virtual private server, a [Droplet](https://www.digitalocean.com/docs/droplets/). You need to create a new `Droplet` to host your Strapi project.
(Additional instructions on creating and using SSH Keys can be found [here](https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/create-with-openssh/).)
- **OPTIONAL:** `Choose a hostname` or leave as-is.
**Digital Ocean** will create your **Droplet** and indicate the progress with a percentage bar. Once this is complete, you may continue to the next steps.
Follow the official [Digital Ocean docs for initial server set-up using Ubuntu 18.04](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04). These docs will have you complete the following actions:
1. [Logging and set up root user access to your server with SSH](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04#step-1-%E2%80%94-logging-in-as-root).
2. [Creating a new user](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04#step-2-%E2%80%94-creating-a-new-user).
3. [Granting Administrative Privileges to the new user](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04#step-3-%E2%80%94-granting-administrative-privileges).
4. [Setting up a basic firewall](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04#step-4-%E2%80%94-setting-up-a-basic-firewall).
5. [Giving your regular user access to the server](https://www.digitalocean.com/community/tutorials/initial-server-setup-with-ubuntu-18-04#step-5-%E2%80%94-enabling-external-access-for-your-regular-user) **with SSH key authentication**.
6. You will install `Node.js` using the instructions in section **Install Node using a PPA** from the official [Digital Ocean docs for installing a production ready Node.js server](https://www.digitalocean.com/community/tutorials/how-to-install-node-js-on-ubuntu-18-04#installing-using-a-ppa).
After completing the steps to **install Node.js, NPM and the "build-essential package"**, you will manually change npm's default directory. The following steps are based on [how to resolve access permissions from npmjs.com](https://docs.npmjs.com/resolving-eacces-permissions-errors-when-installing-packages-globally):
- Create a `.npm-global` directory and set the path to this directory for `node_modules`
```bash
cd ~
mkdir ~/.npm-global
npm config set prefix '~/.npm-global'
```
- Create (or modify) a `~/.profile` file and add this line:
```bash
sudo nano ~/.profile
```
Add this line.
```ini
export PATH=~/.npm-global/bin:$PATH
```
- Lastly, update your system variables:
```bash
source ~/.profile
```
You are now ready to continue to the next section.
A convenient way to maintain your Strapi application and update it during and after initial development is to use [Git](https://git-scm.com/book/en/v2/Getting-Started-About-Version-Control). In order to use Git, you will need to have it installed on your Droplet. Droplets should have Git installed by default, so you will first check if it is installed and if it is not installed, you will need to install it.
2.**OPTIONAL:** Install Git. **NOTE:** Only do if _not installed_, as above. Please follow these directions on [how to install Git on Ubuntu 18.04](https://www.digitalocean.com/community/tutorials/how-to-install-git-on-ubuntu-18-04).
3. Complete the global **username** and **GitHub** settings: [Setting up Git](https://www.digitalocean.com/community/tutorials/how-to-install-git-on-ubuntu-18-04#setting-up-git)
After installing and configuring Git on your Droplet. Please continue to the next step, [installing a database](#install-the-database-for-your-project).
Digital Ocean has excellent documentation regarding the installation and use of the major databases that work with Strapi. The previous steps above should all be completed prior to continuing. You can find links, and any further instructions, to each database guide below:
1. [Install PostgresSQL on Ubuntu 18.04](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-18-04)(Through **Step 4** - Creating a New Database).
Complete the steps to [install PostgreSQL](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-18-04#step-1-%E2%80%94-installing-postgresql), [add a user](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-18-04#step-3-%E2%80%94-creating-a-new-role) and [create a database](https://www.digitalocean.com/community/tutorials/how-to-install-and-use-postgresql-on-ubuntu-18-04#step-4-%E2%80%94-creating-a-new-database).
2. In order to connect to a PostgreSQL database with Strapi, it needs either to have a password, or specifically state there is no password by noting a empty string. Follow these commands from your terminal to `alter` the `user` you created and `add a password`:
**Note:** The `pg` package is automatically installed locally if you choose `PostgreSQL` as the initial database choice when you first set-up Strapi.
You will need the **database name**, **username** and **password** to continue to the next step of [configuring that database.json file](#local-development-configuration).
In your code editor, you will need to edit a file called `database.json`. Replace the contents of the file with the following, but change the `username`, `password` and `database` to match your installation.
[PM2 Runtime](https://pm2.io/doc/en/runtime/overview/?utm_source=pm2&utm_medium=website&utm_campaign=rebranding) allows you to keep your Strapi project alive and to reload it without downtime.
Ensure you are logged in as a **non-root** user. You will install **PM2** globally:
Follow the steps below to have your app launch on system startup. (**NOTE:** These steps are modified from the Digital Ocean [documentation for setting up PM2](https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-18-04#step-3-%E2%80%94-installing-pm2).)
[PM2] Successfully saved in /home/your-name/.pm2/dump.pm2
```
- **OPTIONAL**: You can test to see if the script above works whenever your system reboots with the `sudo reboot` command. You will need to login again with your **non-root user** and then run `pm2 list` and `systemctl status pm2-your-name` to verify everything is working.
- You will need to configure an `ecosystem.config.js` file. It will be used by `pm2` to restart your project whenever any changes are made to files within the Strapi file system itself (such as when an update arrives from GitHub). You can read more about this file [here](https://pm2.io/doc/en/runtime/guide/development-tools/).
`pm2` is now set-up to use an `econsystem.config.js` to manage restarting your application upon changes. This is a recommended best practice. Continue below to configure the `webhook`.
Providing that your project is set-up on GitHub, you will need to configure your **Strapi Project Repository** with a webhook. The following articles provide additional information to the steps below: [GitHub Creating Webhooks Guide](https://developer.github.com/webhooks/creating/) and [Digital Ocean Guide to GitHub WebHooks](https://www.digitalocean.com/community/tutorials/how-to-use-node-js-and-github-webhooks-to-keep-remote-projects-in-sync).
- You will need to access the `Settings` tab for your `Strapi Project Repository`:
1. Navigate and click to `Settings` for your repository.
2. Click on `Webhooks`, then click `Add Webhook`.
3. The fields are filled out like this:
- Payload URL: Enter `http://your-ip-address:8080`
- Content type: Select `application/json`
- Which events would you like to trigger this webhook: Select `Just the push event`
- Secret: Enter `YourSecret`
- Active: Select the checkbox
4. Review the fields and click `Add Webhook`.
- Next, you need to create a `Webhook Script` on your server. These commands create a new file called `webhook.js` which will hold two variables:
- In the `nano` editor, copy/paste the following script, but make sure to replace `your_secret_key` and `repo` with the values that correspond to your project, then save and exit. **NOTE:** Earlier in this guide, there is a optional [recommended step](#the-ecosystem-config-js-file) to create an `ecosystem.config.js` file to manage your application restarting function.
(This script creates a variable called `PM2_CMD` which is used after pulling from GitHub to update your project. The script first changes to the home directory and then runs the variable `PM2_CMD` as `pm2 restart strapi`. If the project uses the `ecosystem.config.js` keep your `ecosystem.config.js` as the point of starting your application and use the alternative below. **PLEASE SEE COMMENTS IN THE CODE**.)
Earlier you setup `pm2` to start the services (your **Strapi project**) whenever the **Droplet** reboots or is started. You will now do the same for the `webhook` script.
- You may test your **webhook** by following the instructions [here](https://www.digitalocean.com/community/tutorials/how-to-use-node-js-and-github-webhooks-to-keep-remote-projects-in-sync#step-4-testing-the-webhook).
- You can **add a domain name** or **use a subdomain name** for your Strapi project, you will need to [install NGINX and configure it](https://www.digitalocean.com/community/tutorials/how-to-install-nginx-on-ubuntu-18-04).
- To **install SSL**, you will need to [install and run Certbot by Let's Encrypt](https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04).
- Set-up [Nginx with HTTP/2 Support](https://www.digitalocean.com/community/tutorials/how-to-set-up-nginx-with-http-2-support-on-ubuntu-18-04) for Ubuntu 18.04.
Your `Strapi` project has been installed on a **Digital Ocean Droplet** using **Ubuntu 18.04**.
This is a step-by-step guide for deploying a Strapi project to [Heroku](https://www.heroku.com/). Databases that work well with Strapi and Heroku are provided instructions on how to get started.
If you plan to use **MongoDB** with your project, [refer to the create a Strapi project with MongoDB section of the documentation](/3.x.x/guides/databases.html#install-mongodb-locally) then, jump to step 4.
**Note:** When you use `--quickstart` to create a Strapi project locally, a **SQLite database** is used which is not compatible with Heroku. Therefore, another database option [must be chosen](#_6-heroku-database-set-up).
(You can use `heroku create custom-project-name`, to have Heroku create a `custom-project-name.heroku.com` URL. Otherwise, Heroku will automatically generating a random project name (and URL) for you.)
Your local development environment is now set-up and configured to work with Heroku. You have a new Strapi project and a new Heroku app ready to be configured to work with a database and with each other.
Below you will find database options when working with Heroku. Please choose the correct database (e.g. PostgreSQL, MongoDB, etc.) and follow those instructions.
Follow these steps to deploy your Strapi app to Heroku using **PostgreSQL**:
##### 1. Install the [Heroku Postgres addon](https://elements.heroku.com/addons/heroku-postgresql) for using Postgres.
To make things even easier, Heroku provides a powerful addon system. In this section, you are going to use the Heroku Postgres addon, which provides a free "Hobby Dev" plan. If you plan to deploy your app in production, it is highly recommended to switch to a paid plan.
`Path: ./my-project/`
```bash
heroku addons:create heroku-postgresql:hobby-dev
```
##### 2. Retrieve database credentials
The add-on automatically exposes the database credentials into a single environment variable accessible by your app. To retrieve it, type:
This should print something like this: `DATABASE_URL: postgres://ebitxebvixeeqd:dc59b16dedb3a1eef84d4999sb4baf@ec2-50-37-231-192.compute-2.amazonaws.com: 5432/d516fp1u21ph7b`.
Strapi expects a variable for each database connection configuration (host, username, etc.). So, from the url above, you have to set several environment variables in the Heroku config:
(Using Strapi and MongoDB requires different set-up and different configuration steps. You cannot use `--quickstart` to develop a `MongoDB` Strapi project.)
Please follow these steps the **deploy a Strapi app with MongoDB on Heroku**.
When you [set-up your MongoDB Atlas database](/3.x.x/guides/databases.html#install-on-atlas-mongodb-atlas) you created and noted the five key/value pairs that correspond to your **MongoDB Atlas** database. These five keys are: `DATABASE_NAME`, `DATABASE_USERNAME`, `DATABASE_PASSWORD`, `DATABASE PORT`, and `DATABASE_HOST`.
Strapi expects a variable for each database connection detail (host, username, etc.). So, from **MongoDB Atlas**, you have to set the environment variables in the Heroku config (for **DATABASE_HOST** you need to surround the URL with **""**, and set **DATABASE_PORT** to nothing):
The deployment may take a few minutes. At the end, logs will display the url of your project (e.g. `https://mighty-taiga-80884.herokuapp.com`). You can also open your project using the command line:
`Path: ./my-project/`
```bash
heroku open
```
If you see the Strapi Welcome page, you have correctly set-up, configured and deployed your Strapi project on Heroku. You will now need to set-up your `admin user` as the production database is brand-new (and empty).
You can now continue with the [Tutorial - Creating an Admin User](/3.x.x/getting-started/quick-start-tutorial.html#_3-create-an-admin-user), if you have any questions on how to proceed.
::: warning NOTE
For security reasons, the Content Type Builder plugin is disabled in production. To update content structure, please make your changes locally and deploy again.
When Strapi is deployed to Heroku, Heroku sets the environment variable to `NODE_ENV=production`. In `production mode` Strapi disables the content-type builder (for security reasons). Additionally, if you wanted to change the default production mode in Heroku, it wouldn't work as the file system is temporary. Strapi writes files to the server when you update the content-types and these updates would disappear when Heroku restarts the server.
Therefore, modifications that require writing to model creation or other json files, e.g. creating or changing content-types, require that you make those changes on your dev environment and then push the changes to Heroku.
As you continue developing your application with Strapi, you may want to use [version control](https://devcenter.heroku.com/articles/github-integration), or you can continue to use `Git push heroku master` to commit and push changes to Heroku directly.
