2. create s3 config file

cat > s3.cfg << EOF
[default]
access_key = 0a09f306baa04358aa88e50c4853329f
secret_key = b15fdf7a8ed947f7afe6fa3b01a376cc
host_base = 127.0.0.1:8080
host_bucket = 127.0.0.1:8080
use_https = false

EOF

3. use s3cmd

# create a bucket
$ s3cmd -c s3.cfg mb s3://config
Bucket 's3://config/' created

# upload the config file
$ s3cmd -c s3.cfg put s3.cfg s3://config/s3.cfg 
upload: 's3.cfg' -> 's3://config/s3.cfg'  [1 of 1]

# list all objects
$ s3cmd -c s3.cfg la
