Getting Started with Nx Private Cloud

Nx Private Cloud is a docker image that can be deployed to your cloud. This version keeps all data on your cloud, except for billing and utilization data that's sent to the Nx Cloud API to enable an integrated billing experience.

For companies who need complete control of data, with no external API calls, the Nx Enterprise is for you.

Nx Cloud consists of 3 parts:

The stateless Nx Cloud service
MongoDB database
File server

By default, the container created by the nxprivatecloud/nxcloud image will create all three: the service, the database, and the file server. Using a single container is the easiest way to set it up, but it isn't the most robust way to run Nx Cloud.

When running everything together, you won't be able to run more than one instance of the Nx Cloud container. So even though it is not required, we recommend you to run the MongoDB separately (see below how to do it).

The instructions will go through running everything together first, and then, at the end, will talk about running the database and the file server separately.

The instructions will use Docker commands, but you can also deploy Nx Cloud to a Kubernetes cluster (see here for more information).

Running Nx Private Cloud

Step 1: Pull the Image

> docker pull nxprivatecloud/nxcloud

To update the version of Nx Private Cloud, pull the new version of the image and run it against the same mount (see below).

Step 2: Create a Container

Depending on how your infrastructure is set up, you can either run Nx Private Cloud using HTTPS or HTTP. If you have a proxy/load-balancer in front of Nx Cloud, you will likely want to run Nx Private Cloud using HTTP (the proxy/load-balancer will handle TLS). Otherwise, you will likely want to run Nx Private Cloud using HTTPS.

To create a container:

You will need to create a directory on the host machine where data will be stored. (This is not necessary if you are running mongo yourself. See below.)
You will need to know the URL that the private cloud can be accessed by (see NX_CLOUD_APP_URL below).
- NX_CLOUD_APP_URL should be accessible from your CI and dev machines.
- NX_CLOUD_APP_URL can be set with an HTTP or HTTPS url. In a case where you are using a proxy/load-balancer, you can still put HTTPS (the url will be resolved by the proxy before hitting the app).
- NX_CLOUD_APP_URL is likely to be an external IP/domain of the load balancer.
If you are running Nx Private Cloud using HTTPS, you need to generate or obtain an SSL certificate and an SSL private key.

Once you obtain all the needed information, you can run the following:

Using HTTPS

> docker create --name cloud \

        -p 443:8081 \
        -e CERT_KEY="$(cat ./tools/certs/key.pem)" \
        -e CERT="$(cat ./tools/certs/cert.pem)" \
        -e NX_CLOUD_APP_URL="https://cloud.myorg.com" \
        -e ADMIN_PASSWORD=admin \
        -v /data/private-cloud:/data nxprivatecloud/nxcloud:latest

Using HTTP (no proxy)

> docker create --name cloud \

        -p 80:8081 \
        -e NX_CLOUD_APP_URL="http://cloud.myorg.com" \
        -e ADMIN_PASSWORD=admin \
        -v /data/private-cloud:/data nxprivatecloud/nxcloud:latest

Using HTTPS via proxy

> docker create --name cloud \

        -p 80:8081 \
        -e NX_CLOUD_APP_URL="https://cloud.myorg.com" \
        -e ADMIN_PASSWORD=admin \
        -v /data/private-cloud:/data nxprivatecloud/nxcloud:latest

Let's see what those options mean:

443:8081 maps the internal port 8081 to 443, so it can be accessed in the browser without specifying the port. 80:8081 works the same way when you use HTTP instead of HTTPS.
CERT_KEY and CERT contain the values of private key and cert. The file extensions of the cert and key files can be different, but as long as they are in the PEM format (which is the case if you use, for instance, OpenSSL), the command will work.
NX_CLOUD_APP_URL is the URL the cloud can be accessed by (e.g., https://nxcloud.privateurl.com). Important: Unless you are experimenting, it won't be localhost. It has to be the URL that your CI and your developer machine can reach. Also note, there is no trailing slash in the URL.
ADMIN_PASSWORD contains the password of the admin user. The admin user is created the first time you run cloud, you can remove this env variable after that. Instead of an admin password, you can also follow the instructions here to set-up GitHub auth.
-v /data/private-cloud:/data sets up the volume where the data is stored. /data/private-cloud refers to a folder on your machine, /data is the shareable folder from the Docker image.

Step 3: Run the Container

Once you create the container, you can start it using:

> docker start cloud

Imagine NX_CLOUD_APP_URL is set to https://nxcloud.privateurl.com.

Now, go to https://nxcloud.privateurl.com to see cloud running. You can log into the account using admin/ADMIN_PASSWORD.

Step 4: Connect Your Workspace

Run NX_CLOUD_API=https://nxcloud.privateurl.com nx g @nrwl/nx-cloud:init. Click on the link to connect the workspace to your admin account.

Step 5: Configure Billing

Go to https://nxcloud.privateurl.com, select the workspace, click on Billing. You will see a link redirecting you to https://nx.app, where you can register your credit card.

Note, it usually takes a few minutes for the billing information to sync up.

As stated above, Nx Private Cloud will store all your artifacts and the information about runs on premises, but will report utilization to https://api.nrwl.io.

Optional step 6: Set-up GitHub auth

Follow the instructions here to set-up GitHub OAuth authentication so you can invite other members in your team to the workspace.

Optional step 7: Set-up GitHub Pull Request integration

You can optionally configure private cloud to post build stats directly on your GitHub pull requests.

Optional step 8: Setting Up Proxy

If your container cannot access api.nrwl.io directly and has to talk via a proxy, you can add -e HTTPS_PROXY="https://myproxy.myorg.com" to the container creation command.

Running the Mongo Database Separately (Recommended)

Nx Cloud uses MongoDB to store its metadata. By default, Nx Private Cloud is going to start a MongoDB instance and store its data in the provided volume. But you can also tell Nx Private Cloud to use a different MongoDB instance (e.g., if you are using MongoDB Atlas or Cosmos DB). To do this, provision the NX_CLOUD_MONGO_SERVER_ENDPOINT env variable when creating a container, like so:

-e NX_CLOUD_MONGO_SERVER_ENDPOINT="mongodb://domain-with-mongo:27017/nrwl-api"

By default, Nx Cloud requires Mongo 4.2+. If you are using an older version of Mongo (for instance, if you are using Cosmos DB), please add

-e NX_CLOUD_USE_MONGO42=false

Using MongoDB Kubernetes Operator

The MongoDB team maintains the open source MongoDB Kubernetes Operator. You can use it to set up your own deployment of MongoDB. See the Nx Cloud and Kubernetes page for more information.

Using CosmosDB

If you are deploying to Azure, you might have access to CosmosDB. See here for more information.

Using Mongo Atlas

Mongo Atlas is a great option for deploying MongoDB.

Using External File Storage

By default, Nx Private Cloud is going to start a file server and store the cached artifacts in the provided volume. But you can also configure Nx Private Cloud to use an external file storage. At the moment, only S3 and Azure Blob are supported.

Using S3/Minio

To configure S3 as a file storage, provision the AWS_S3_ACCESS_KEY_ID, AWS_S3_SECRET_ACCESS_KEY, and AWS_S3_BUCKET env variables when creating the Nx Cloud docker container, like so:

-e AWS_S3_ACCESS_KEY_ID="SOMEKEY"
-e AWS_S3_SECRET_ACCESS_KEY="SOMESECRETKEY"
-e AWS_S3_BUCKET="nx-cache-bucket-name"

If you are using an accelerated bucket, add: -e AWS_S3_ACCELERATED=true

If you are using a local S3 installation (e.g., Minio), you can set the endpoint as follows:

-e AWS_S3_ENDPOINT="https://local-installation.myorg.com"
-e AWS_S3_ACCESS_KEY_ID="SOMEKEY"
-e AWS_S3_SECRET_ACCESS_KEY="SOMESECRETKEY"
-e AWS_S3_BUCKET="nx-cache-bucket-name"

Note: Remember to set a cache item expiration time. The default is currently 4 weeks. If you would like to keep items for longer, for example for 8 weeks, please remember to set the NX_CACHE_EXPIRATION_PERIOD_IN_DAYS=56 env variable as well, so the container knows when to expire the Mongo cache entries as well.

Using Azure

To configure Azure Blob as a file storage, provision the AZURE_CONNECTION_STRING, AZURE_CONTAINER env variables when creating the Nx Cloud docker container, like so:

-e AZURE_CONNECTION_STRING="SOME-CONNECTION-STRING"
-e AZURE_CONTAINER="files"

To obtain the AZURE_CONNECTION_STRING value go to your "Storage Account" and click on "Access Keys". You will also need to create a container in your storage account before starting the Nx Cloud container.

If you use an external file storage and an external MongoDB instance, you don't have to provision the volume.

Note: See note above about setting a cache expiration time. For Azure blob storage, see this guide.
