ToolJet can connect to Amazon S3 buckets and perform various operation on them.
</div> <div style={{paddingTop:'24px', paddingBottom:'24px'}}>To establish a connection with the Amazon S3 data source, you can either click on the +Add new Data source button located on the query panel or navigate to the Data Sources page from the ToolJet dashboard.
ToolJet supports connecting to AWS S3 using IAM Access Keys, AWS Instance Credentials or AWS ARN Role.
If you are using IAM Access Keys, you will need to provide the following details:
It is recommended to create a new IAM user for the database so that you can control the access levels of ToolJet.
<div style={{textAlign: 'left'}}> </div>To connect to AWS S3 using AWS Instance Credentials, select the Use AWS Instance Credentials. This will use the IAM role attached to the EC2 instance where ToolJet is running. To access the metadata service of an ECS container and the EC2 instance, we use the WebIdentityToken parameter which is obtained from a successful login with an identity provider.
<div style={{textAlign: 'left'}}> </div>If you are using AWS ARN Role, you will need to provide the following details:
Click on Test Connection button to verify if the credentials are correct and that the database is accessible to ToolJet server. Click on Save button to save the data source.
:::tip You can now connect to different S3 Hosts using custom endpoints. :::
</div> <div style={{paddingTop:'24px', paddingBottom:'24px'}}>Click on +Add button of the query manager and select the data source added in the previous step as the data source. Select the operation that you want to perform, fill in the required parameters and click on Run button to run the query.
<div style={{textAlign: 'left'}}> </div>:::info Query results can be transformed using transformations. Read our transformations documentation. :::
</div> <div style={{paddingTop:'24px', paddingBottom:'24px'}}>You can create query for AWS S3 data source to perform several actions such as:
You can create a new bucket in your S3 by using this operation.
You can read an object in a bucket by using this operation.
You can use this operation to upload objects(files) to your S3 bucket.
You can use this operation to remove an object from your S3 bucket.
This operation will list all the buckets in your S3. This does not require any parameter.
<div style={{textAlign: 'left'}}> </div> </div> <div style={{paddingTop:'24px', paddingBottom:'24px'}}>This operation will fetch the list of all the files in your bucket. It requires the following parameters:
Next Continuation Token indicates Amazon S3 that the list is being continued on this bucket with a token. ContinuationToken is obfuscated and is not a real key.:::info
Next Continuation Token
For listing a bucket for objects that begin with a specific character or a prefix, then use the Offset parameter. For example, if you want to list all the objects that begin with a, then set the Offset parameter to a. Similarly, if you want to list all the objects that begin with ab, then set the Offset parameter to ab.
The Next Continuation Token is used to list the next set of objects in a bucket. It is returned by the API when the response is truncated. The results will contain Next Continuation Token if there are more keys in the bucket that satisfy the list query. To get the next set of objects, set the Next Continuation Token parameter and run the query again.
The results will continue from where the last listing finished.
:::
The object owner can optionally share objects with others by creating a presigned URL, using their own security credentials, to grant time-limited permission to download the objects.
The presigned URLs are useful if you want your user/customer to be able to upload a specific object to your bucket, but you don't require them to have AWS security credentials or permissions.
