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

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.

Is there some way to do this.

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

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.

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

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.

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.

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

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

You can make all objects in a public range, this link has more information: https://cloud.google.com/storage/docs/access-control/making-data-public

If you can't, in your console, log into your bucket and click "Edit bucket permissions" - Enter allUsers in Add Members. Then Select Role > Storage > Storage Object Viewer

Apr, 2022 Update:

You can allow all users to read files in your bucket.

For example, in Bucket details, click "PERMISSIONS" then "ADD":

Then, type "allUsers":

Then, choose the role "Storage Legacy Object Reader" so that all users can read files:

Then, click "SAVE":

Then, you will be asked as shown below so click "ALLOW PUBLIC ACCESS":

Finally, you can allow all users to read files in your bucket:
