Modify HUMMIX parameters

During the operation of HUMMIX system, there may be a need to change or reconfigure a particular component of the application. For example, it might be necessary to modify service settings (change email server settings), connection parameters to the application, configure additional functionalities, etc.

The process of modifying application parameters consists of two steps:

Step 1: Make changes to the configuration file values-hummix.yaml

Changes are made to the existing configuration file values-hummix.yaml, which was obtained and filled out during the installation of HUMMIX.

Attention

Before making changes to the values-hummix.yaml file, it is recommended to create a backup copy of it. Incorrect changes to the parameters in this file can lead to the HUMMIX application becoming inoperable.

To load the latest file with parameters, run:

helm repo update
helm show values hummix/hummix > values-hummix-new.yaml

As a result of executing the command, the values-hummix-new.yaml file with the parameters of the latest version will be downloaded.

To load the file with the parameters of a certain system version, add the --version flag to the helm show values hummix/hummix command:

helm repo update
helm show values hummix/hummix --version <hummix-chart-version> > values-hummix-new.yaml

Where <hummix-chart-version> is the system version required.

As a result of executing the command, the values-hummix-new.yaml file with the parameters of the version specified will be downloaded.

To read the file with parameters that was used in HUMMIX installation, run:

helm [-n namespace] list
helm [-n namespace] get values hummix > values-hummix-installed.yaml

Uncomment and edit the parameters in the values-hummix.yaml configuration file and save the changes.

Optional environment variables

In the values-hummix.yaml file, you can control certain features of the HUMMIX application, such as the Jaeger service address for sending traces, the expiration date for links to upload objects to S3, and so on.

For this, you can use environment variables which are specified in the following parameters:

hummix.global.extraEnv to apply variable settings to all system services.
hummix.<service>.extraEnv to apply variable settings to a specific service. Replace <service> with the service name.

If an environment variable is set globally and in a specific service block, the value from hummix.<service>.extraEnv is used.

Example of configuring the HUMMIX_JAEGER_ENDPOINT parameter

In the table below, you can find a list of available environment variables that are configured in the extraEnv parameter.

Name	Description
HUMMIX_JAEGER_ENDPOINT	The Jaeger service endpoint to which tracing data is sent.
UPLOAD_LINK_DURATION	The expiration date of technical API links for uploading objects to S3. These are used by microservices to transfer files to storage. Default value: 120m. The value can be specified in minutes or hours.
DOWNLOAD_LINK_DURATION	The expiration date of technical API links for downloading objects from S3. These are used by microservices to retrieve files from storage. Default value: 480m. The value can be specified in minutes or hours. Changing the default expiration date for S3 links may be necessary if you work with files through integrations with external services. A new value is set to ensure that file uploads and downloads are completed before the link expires.
HUMMIX_ASPOSEACTIONS_FONT_UPDATE_ENABLE	Enable font uploading and updating.
The value is set as follows: global: extraEnv: HUMMIX_ASPOSEACTIONS_FONT_UPDATE_ENABLE: "true"
HUMMIX_ASPOSEACTIONS_FONT_UPDATE_PERIOD_IN_MINUTES	Set the font update frequency. The default value is 30m.
The value is set as follows: global: extraEnv: HUMMIX_ASPOSEACTIONS_FONT_UPDATE_PERIOD_IN_MINUTES: 30m

Step 2: Apply new parameters for HUMMIX

You can update parameters for HUMMIX in two ways: online and offline.

Update parameters online

Determine the chart version with which the HUMMIX application was installed or updated:

helm list [-n namespace]

Command execution example:

change-settings-enterprise-1

After the command execution, you see the chart version information in the version string. Save this value for the next step.

Update the HUMMIX parameters using the values-hummix.yaml configuration file. To do this, execute the following command specifying the installed chart version for the --version flag instead of <hummix-chart-version>:

helm upgrade --install hummix hummix/hummix -f values-hummix.yaml --version <hummix-chart-version> --timeout=30m --wait [-n namespace]

Update parameters offline

Navigate to the directory with the chart with which the HUMMIX application was installed or updated and execute the command:

helm upgrade --install hummix ./hummix -f values-hummix.yaml --timeout=30m --wait [-n namespace]

It takes about 10-30 minutes to update the parameters. Wait for it to complete.
