How do you make many files public in Google Cloud Storage?

Question

I have 1000 files in Google Cloud Storage to make public, or in general a directory hierarchy.

In the Web UI, I can only seem to make one at a time public.

Answer 1

The easiest way to accomplish this would be by using a console.

Click on "Edit bucket permissions"

Enter allUsers in Add Members. Then Select Role > Storage > Storage Object Viewer

Attention! This will give read permission to all the people on the internet to all the objects in that selected bucket.

Answer 2

Current (Oct/2017) documentation about Hosting a Static Website found here points to:

gsutil acl ch -r -u AllUsers:R gs://bucket-name

Where the -r does the recursive trick and -u AllUsers:R gives the public read access.

Answer 3

You can make all objects in a bucket public. Here's the link.

1. Open the Cloud Storage browser in the Google Cloud Platform Console.
2. In the list of buckets, click on the name of the bucket that you want to make public.
3. Select the Permissions tab near the top of the page.
4. Click the Add members button.
   The Add members dialog box appears.
5. In the Members field, enter allUsers.
6. In the Roles drop down, select the Storage sub-menu, and click the Storage Object Viewer option.
7. Click Add.

Once shared publicly, a link icon appears for each object in the public access >column. You can click on this icon to get the URL for the object.

Answer 4

Run gsutil -m acl set -R -a public-read gs://bucket

• The -m issues multiple requests at the same time.
• The -R issues requests for every object in your bucket.
• The -a issues requests for every version of every object.

See gsutil help acl for more info.

At the API layer gsutil issues the following HTTP request:

PUT /bucket/obj?acl HTTP/1.1
Host: storage.googleapis.com
x-goog-acl: public-read

You can see this by using the -D flag with gsutil:

gsutil -D setacl public-read gs://bucket/obj

Answer 5

To copy and paste on Erik's behalf, this worked consistently for me:

Making groups of objects publicly readable

To make all objects in a bucket publicly readable:

CONSOLEGSUTILREST APIS Use the gsutil iam ch command, replacing [VALUES_IN_BRACKETS] with the appropriate values:

 gsutil iam ch allUsers:objectViewer gs://[BUCKET_NAME]

Answer 6

When you run: gsutil -m acl set -R -a public-read gs://bucket you define public read for all the objects currently in your bucket, but when you upload new files they wont be public by default.

What I found is that is worth to define a bucket default acl as public-read gsutil defacl set public-read gs://bucket
