how to copy s3 object from one bucket to another using python boto3
Question:
I want to copy a file from one s3 bucket to another. I get the following error:
s3.meta.client.copy(source,dest)
TypeError: copy() takes at least 4 arguments (3 given)
I’am unable to find a solution by reading the docs. Here is my code:
#!/usr/bin/env python
import boto3
s3 = boto3.resource('s3')
source= { 'Bucket' : 'bucketname1','Key':'objectname'}
dest ={ 'Bucket' : 'Bucketname2','Key':'backupfile'}
s3.meta.client.copy(source,dest)
Answers:
This is the syntax from docs:
import boto3
s3 = boto3.resource('s3')
copy_source = {
'Bucket': 'mybucket',
'Key': 'mykey'
}
s3.meta.client.copy(copy_source, 'otherbucket', 'otherkey')
Since you are using s3 service resource, why not use its own copy
method all the way?
#!/usr/bin/env python
import boto3
s3 = boto3.resource('s3')
source= { 'Bucket' : 'bucketname1', 'Key': 'objectname'}
dest = s3.Bucket('Bucketname2')
dest.copy(source, 'backupfile')
You can try:
import boto3
s3 = boto3.resource('s3')
copy_source = {
'Bucket': 'mybucket',
'Key': 'mykey'
}
bucket = s3.Bucket('otherbucket')
bucket.copy(copy_source, 'otherkey')
or
import boto3
s3 = boto3.resource('s3')
copy_source = {
'Bucket': 'mybucket',
'Key': 'mykey'
}
s3.meta.client.copy(copy_source, 'otherbucket', 'otherkey')
Note the difference in the parameters
