Access files stored on Amazon S3 through web browser

Question

Current Situation  I have a project on Github that builds after every commit on Travis-CI  After each successful build Travis uploads the artifacts to an S3 bucket  Is there some way for me to easily let anyone access the files in the bucket  I know I could generate a read-only access key  but it d be easier for the user to access the files through their web browser   I have website hosting enabled with the root document of     set      However  I still get an 403 Forbidden when trying to go to the bucket s endpoint     The Question  How can I let users easily browse and download artifacts stored on Amazon S3 from their web browser  Preferably without a third-party client

I found this related question  Directory Listing in S3 Static Website  As it turns out  if you enable public read for the whole bucket  S3 can serve directory listings  Problem is they are in XML instead of HTML  so not very user-friendly   There are three ways you could go for generating listings    Generate index html files for each directory on your own computer  upload them to s3  and update them whenever you add new files to a directory  Very low-tech  Since you re saying you re uploading build files straight from Travis  this may not be that practical since it would require doing extra work there  Use a client-side S3 browser tool    s3-bucket-listing by Rufus Pollock s3-file-list-page by Adam Pritchard  Use a server-side browser tool    s3browser  PHP  s3index Scala  Going by the existence of a Procfile  it may be readily deployable to Heroku  Not sure since I don t have any experience with Scala

I had the same problem and I fixed it by using the    new context menu  Make Public   Go to https   console aws amazon com s3 home  select the bucket and then for each Folder or File  or multiple selects  right click and  make public

You can use a bucket policy to give anonymous users full read access to your objects   Depending on whether you need them to LIST or just perform a GET  you ll want to tweak this    I e  permissions for listing the contents of a bucket have the action set to  s3 ListBucket     http   docs aws amazon com AmazonS3 latest dev AccessPolicyLanguage UseCases s3 a html  Your policy will look something like the following   You can use the S3 console at http   aws amazon com console to upload it         Version   2008-10-17      Statement          Sid   AddPerm          Effect   Allow          Principal                  AWS                          Action    s3 GetObject           Resource    arn aws s3   bucket                          If you re truly opening up your objects to the world  you ll want to look into setting up CloudWatch rules on your billing so you can shut off permissions to your objects if they become too popular
