I have a project in which I need to use gcloud commands, I need to build with the proper credentials, seems gcloud commands don't use the variable GOOGLE_APPLICATION_CREDENTIALS, so I set the auth in RUN step in docker

FROM google/cloud-sdk
COPY . usr/src/app
WORKDIR /usr/src/app 
RUN gcloud auth activate-service-account --key-file=/usr/src/app/credentials.json

but when I build the image and enter to the container I have no access to gcloud commands, lets say

gcloud projects list

I have the next answer

WARNING: Could not open the configuration file: [/root/.config/gcloud/configurations/config_default]. ERROR: (gcloud.projects.list) You do not currently have an active account selected.

credentials are inside the container because if I do manually I can run the next command and everything works well.

gcloud auth activate-service-account --key-file=/usr/src/app/credentials.json

how can add the credentials to exist by default in build?, does the RUN step may not take effect when building the image.

You are correct, gcloud does not check GOOGLE_APPLICATION_CREDENTIALS.

I think you're not using the Google-approved container image: Google Cloud SDK Docker

See Usage for a good way to mount service account credentials into the container.
