Installing CityLens

Important note:

All passwords and keys in this section are given for illustration purposes.

During a real installation, it is recommended to use more complex and reliable passwords.

1. Before installing

Consider getting familiar with:
Make sure the necessary preparation steps are completed:

Collect the necessary information that was set or retrieved on previous steps:

Object	Example value	How to get value
Docker Registry mirror endpoint	`artifacts.example.com`	See Fetching installation artifacts
Kubernetes secret for accessing Docker Registry	`onpremise-registry-creds`	See Fetching installation artifacts
Installation artifacts S3 storage domain name	`artifacts.example.com`	See Fetching installation artifacts
Bucket name for installation artifacts	`onpremise-artifacts`	See Fetching installation artifacts
Installation artifacts access key	`AKIAIOSFODNN7EXAMPLE`	See Fetching installation artifacts
Installation artifacts secret key	`wJalrXUtnFEMIK7MDENGbPxRfiCYEXAMPLEKEY`	See Fetching installation artifacts
Path to the manifest file	`manifests/1640661259.json`	See Fetching installation artifacts
License service endpoint	`https://license.svc`	See Installing License service
MapGL JS API endpoint	`mapgl.example.local`	See Installing maps API
Pro API endpoint	`https://pro-api.host`	See Installing Urbi Pro

Make sure that the resource requirements specified in the Helm chart are met. For more information on how to do this, refer to the System requirements document.

Note

Contents of the Helm chart described in this chapter are relevant for the latest On-Premise version (see Release notes). To find parameters for earlier versions, open values.yaml on GitHub and enter the required version number (for example, 1.18.0) in the tag switcher on the left.
Choose domain names.

Example:
- Domain name for CityLens service – UI for viewing uploaded tracks: http://citylens-web.host
- Domain name for CityLens API, where the mobile application connects and uploads tracks: http://citylens-api.host

2. Prepare infrastructure

Configure PostgreSQL

Place a PostgreSQL cluster with the domain name citylens-postgresql.storage.example.local in the private network. This instruction assumes that the cluster works on the standard port 5432.

Configure the PostgreSQL cluster for usage as a storage:

Connect to the cluster as a superuser (usually postgres).
Create a database user that will be used for the service. Set a password for the user:
```
create user citylens password citylens;
```

Create a database owned by this user:

create database citylens owner citylens;

Configure S3 storage

Place an S3-compatible storage (for example, Ceph) with the domain name citylens-s3.storage.example.local in the private network. This instruction assumes that the storage works on the standard port 80.

Configure the S3-compatible storage:

Create a user that will be used for the service:
- accessKey: accessKey
- secretAccessKey: secretAccessKey
Remember the credentials for the user.
Choose bucket names that will be used for the service. For example:
- Bucket with main data: onprem-citylens.

Configure Apache Kafka

Place an Apache Kafka storage with the domain name citylens-kafka.storage.example.local in the private network. This instruction assumes that the storage works on the standard port 9092.

Create a user that will be used for the service.:

username: kafka
password: kafka_password

Remember the credentials for the user.

3. Install CityLens

Create a Helm configuration file. See here for more details on the available settings.

The example is prefilled with the necessary data collected on previous steps.
