kendo-ui-license activation in Docker

[Ambarish]

Hi,

The license key works when i activate locally on my machine but it does not when trying the same with Dockerfile. Here's the dockerfile code:

# base image

FROM node:18.17.0 as build

# set working directory

WORKDIR /app

# add `/app/node_modules/.bin` to $PATH

ENV PATH /app/node_modules/.bin:$PATH

ARG KENDO_UI_LICENSE_KEY

ENV KENDO_UI_LICENSE= ${KENDO_UI_LICENSE_KEY}

RUN echo ${KENDO_UI_LICENSE_KEY} > kendo-ui-license.txt

RUN npm install

COPY . /app

RUN npx kendo-ui-license activate

 

RUN ng build --prod

FROM nginx:1.17.4-alpine

## Remove default Nginx website

RUN rm -rf /usr/share/nginx/html/*

# copy artifact build from the 'build environment'

COPY --from=build /app/dist/ui/ /usr/share/nginx/html

 

The docker build gave the following error. Please help. The signature is valid as I have activated the same

llicense key on local machine.

=> [build  9/11] COPY . /app                                                                                     17.9s

i figured it out. The secret needs to be in the build pipeline’s variable and not in library group variable. For soem reason storing it as a secret in library group doesnt work but storing it as a pipeline secret variable works. Hope this helps others

Hi Ambarish,

Thank you for the provided details and shared experience.

I believe this would help others who ended up in a similar situation.

Hi Ambarish,

Ensure that the license key stored in the env variable is valid. To verify this, I would suggest downloading it from here:

https://www.telerik.com/kendo-angular-ui/components/my-license/#toc-downloading-the-license-key

In case the license is activated, but you still see the banner and watermark, consider clearing the cache before activating the license:

https://www.telerik.com/kendo-angular-ui/components/my-license/#toc-i-renewed-my-license-key-but-still-seeing-the-invalid-license-attributes-what-should-i-do

or follow the steps from this article:

https://www.telerik.com/kendo-angular-ui/components/knowledge-base/license-troubleshooting-activation-warning-watermark/

Another approach that helps other customers is to perform some of the actions in a single step for example putting the angular cache clean, license activation, and angular build all into one step.
