How to check if file exists in Google Cloud Storage with the gcloud bash command?-CodePudding

I need to check if a file exists in a gitlab deployment pipeline. How to do it efficiently and reliably?

CodePudding user response：

Use gsutil ls gs://bucket/object-name and check the return value for 0.

If the object does not exist, the return value is 1.

CodePudding user response：

You can add the following Shell script in a Gitlab job :

#!/usr/bin/env bash

set -o pipefail
set -u

gsutil -q stat gs://your_bucket/folder/your_file.csv

PATH_EXIST=$?
if [ ${PATH_EXIST} -eq 0 ]; then
  echo "Exist"
else
  echo "Not Exist"
fi

I used gcloud cli and gsutil with stat command with -q option.

In this case, if the file exists the command returns 0 otherwise 1.
