Error to build AWS Lambda Node 14arm64 with Sharp on a Docker image

I'm changing a node setup from node 14 x64 to node 14 arm64 in an Amazon ECR (Docker) entry.

It build with no problem when I use this image: FROM aws/lambda/nodejs:14 and this command to install sharp RUN npm install --platform=linux sharp

Now I need to use Node 14 arm64 image, but it launches this error while building with Sharp JS (Linux arm 64):

Dockerfile:

FROM public.ecr.aws/lambda/nodejs:14-arm64

# Exec commands
COPY index.js package.json ${LAMBDA_TASK_ROOT}
COPY fonts ${LAMBDA_TASK_ROOT}/fonts/
COPY src ${LAMBDA_TASK_ROOT}/src/

# Commands
RUN npm cache clean --force
RUN rm -rf node_modules
RUN npm install --arch=arm64 --platform=linux sharp

CMD ["index.handler"]

Build command:

docker build -t my-project-v1 .
docker tag my-project-v1:latest {ACCOUNT}.dkr.ecr.us-east-1.amazonaws.com/my-project-v1:latest
docker push {ACCOUNT}.dkr.ecr.us-east-1.amazonaws.com/my-project-v1:latest

Error:

The error message said that the problem is related with libvips: sharp: Installation error: Use with glibc 2.26 requires manual installation of libvips >= 8.11.3. Searching in the official sharp documentation I found that on machines other than Linux x64 (like in your case: Linux arm64), you should ignore global libvips updating the SHARP_IGNORE_GLOBAL_LIBVIPS environment variable:

npm install
SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux sharp

so, you should update your Dockerfile to the following:

FROM public.ecr.aws/lambda/nodejs:14-arm64

# Exec commands
COPY index.js package.json ${LAMBDA_TASK_ROOT}
COPY fonts ${LAMBDA_TASK_ROOT}/fonts/
COPY src ${LAMBDA_TASK_ROOT}/src/

# Commands
RUN npm cache clean --force
RUN rm -rf node_modules

## update the dockerfile with the following lines:
RUN npm install
RUN SHARP_IGNORE_GLOBAL_LIBVIPS=1 npm install --arch=x64 --platform=linux sharp
