Hi, we are trying to setup Pulumi in CI/CD with Go...

Hi, we are trying to setup Pulumi in CI/CD with Google Cloud Build and encountered a weird issue where it is showing the following error about 
Pulumi SDK has not been installed
even though we are indeed running 
yarn install
. Can someone please help?
Copy code
pulumi login <GCP Bucket address>
Logged into <GCP Bucket address>
pulumi preview --cwd=/workspace/identity --stack=identity-prod --refresh --non-interactive
Previewing update (identity-prod):
    pulumi:pulumi:Stack identity-identity-prod  error: It looks like the Pulumi SDK has not been installed. Have you run npm install or yarn install?
    pulumi:pulumi:Stack identity-identity-prod  1 message
Diagnostics:
  pulumi:pulumi:Stack (identity-identity-prod):
    error: It looks like the Pulumi SDK has not been installed. Have you run npm install or yarn install?

I'll add our setup's details (such as cloud build file etc.) in a thread to this comment.
Our setup is as follows: 1. root directory -> sub-directories, with one Pulumi project per sub-directory, e.g. one such sub-directory/Pulumi project is 
identity
. 2. In Google Cloud Build, we are running cloud build steps from a 
cloudbuild.yaml
file present in the sub-directory, i.e. from 
identity/cloudbuild.yaml
. 3. The 
identity/cloudbuild.yaml
file looks like the following:
Copy code
steps:
  - name: "<http://gcr.io/cloud-builders/docker|gcr.io/cloud-builders/docker>"
    args: [ "build", "-t", "<http://asia.gcr.io/$PROJECT_ID/|asia.gcr.io/$PROJECT_ID/><repo-name>:$COMMIT_SHA", "."]
  - name: "<http://gcr.io/cloud-builders/docker|gcr.io/cloud-builders/docker>"
    args: ["push", "<http://asia.gcr.io/$PROJECT_ID/|asia.gcr.io/$PROJECT_ID/><repo-name>:$COMMIT_SHA"]
  - name: '<http://asia.gcr.io/$PROJECT_ID/|asia.gcr.io/$PROJECT_ID/><repo-name>:$COMMIT_SHA'
    entrypoint: /bin/bash
    args:
    - '-c'
    - "export BUILD_TYPE=${_BUILD_TYPE} && make ci-login && make ci-up"
    env:
      - 'PROJECT=identity'
      - 'ENV=prod'
    secretEnv: ["GOOGLE_CREDENTIALS"]
secrets:
  - kmsKeyName: <path-to-key>
    secretEnv:
      GOOGLE_CREDENTIALS: <REDACTED>
Note that do run 
yarn install
in the Dockerfile:
Copy code
FROM pulumi/pulumi

WORKDIR /workspace

COPY . .

# add other projects later
RUN yarn --cwd ./identity --frozen-lockfile install
And the 
Makefile
(present in the root of the repo) has the following 
make
commands called from the cloud build file above:
Copy code
ci-login:
	pulumi login <path-to-bucket>

ci-up:
ifeq ($(BUILD_TYPE),preview)
	pulumi preview --cwd=$(PWD)/$(PROJECT) --stack=$(PROJECT)-$(ENV) --refresh --non-interactive
else
	pulumi up --cwd=$(PWD)/$(PROJECT) --stack=$(PROJECT)-$(ENV) --refresh --non-interactive
endif
_BUILD_TYPE
is specified with the value 
preview
in the Google Cloud Build trigger configuration as per the official instructions from https://www.pulumi.com/docs/guides/continuous-delivery/google-cloud-build/
g
Is 
$(PWD)/$(PROJECT)
in your Makefile the same path as 
./identity
as in the Dockerfile?
You could add a 
tree
or 
ls -al node_modules
in one of them to help troubleshoot and see if the yarn install is installing to the expected location.

Thanks, figured it out with your clues and by executing into the container. Basically, the issue was that the 
node_modules
subdirectory was installed to the 
/identity
directory of the docker container. But by default, Google Cloud Build mounts the host filesystem (without 
node_modules
) to 
/workspace
of the docker container and then the current working directory was specified as 
/workspace
in the Dockerfile.
