Get an S3 Object

You can call the get an S3 object command on your S3 client to download a file by specifying the branch.repo.project it lives in. For example, let’s get the test.csv file from master.foo.bar.

aws --endpoint-url http://localhost:30600/ s3 cp s3://master.foo.bar/test.csv .

download: s3://master.foo.bar/test.csv to ./test.csv

mc cp local/master.foo.bar/test.csv .

test.csv:  2.56 MiB / 2.56 MiB  ▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓ 100.00% 1.26 MiB/s 2s

Versioning #

Most operations act on the HEAD of the given branch. However, if your object store library or tool supports versioning, you can get objects in non-HEAD commits by using the commit ID as the S3 object version ID or use the following syntax --bucket <commit>.<branch>.<repo>.<project>

To retrieve the file file.txt in the commit a5984442ce6b4b998879513ff3da17da on the master branch of the repo foo in project bar:

aws s3api get-object --bucket a5984442ce6b4b998879513ff3da17da.master.foo.bar  --profile gcp-pf --endpoint http://localhost:30600 --key file.txt export.txt

aws s3api get-object --bucket master.foo.bar --profile gcp-pf --endpoint http://localhost:30600 --key file.txt --version-id a5984442ce6b4b998879513ff3da17da export.txt
