+ - aws logs describe-log-streams --log-group-name /aws/lambda/{fn name} --query 'logStreams[*].logStreamName' --max-items 1 --order-by LastEventTime --descending | awk -F'"' '$0=$2' | xargs aws logs get-log-events --log-group-name /aws/lambda/{fn_name } --log-stream-name | jq
|
|
|
+ - breakdown:
|
|
|
+ - specify log group name based on fn name
|
|
|
+ - query for 1 item, sorted by most recent
|
|
|
+ - take val between two ""
|
|
|
+ - pass name to xargs to get-log-events
|
|
|
+ - jq to format json
|
|
|
+
|
|
|
+ - commands:
|
|
|
+ - describe-log-groups
|
|
|
+ - describe-log-streams --{log group name}
|
|
|
+ - get-log-events --{log group name} -{log stream name}

+## deleting s3 buckets that have had improper policies attached to them
|
|
|
+- need to use use the aws cli to run 's3api delete-bucket-policy --bucket {bucket name}'
|
|
|
+ - can't use aws console, also can't delete bucket before deleting policy
|
|
|
+- need to use access keys of root account
|
|
|
+ - log in as root acct, generate new pair of access/secret access keys, use it to configure
|
|
|
+ aws-cli in docker, delete key pair, re-config the image to use iam user
|
|
|
+ creds,
|
|
|
+ - see steps below to configure/run docker aws-cli
|
|
|
+- adapting example below, command will be:
|
|
|
+ - (first run config with root creds)
|
|
|
+ - docker run --rm -v $HOME/.aws:/root/.aws amazon/aws-cli s3api delete-bucket-policy --bucket {bucket name}

|
|
+## uploading cors configurations
|
|
|
+ - the xml syntax appears to be deprecated? Though I didn't see this
|
|
|
+ mentioned anywhere.
|
|
|
+ - using the cli put-bucket-cors command solved the issue
|
|
|
+ - sudo docker run --rm -tiv $HOME/.aws:/root/.aws amazon/aws-cli s3api put-bucket-cors --bucket {bucket name} --cors-configuration file:///root/.aws/{config file name}.json
|
|
|
+ - note the triple slash after file
|
|
|
+ - I think 'file://' is needed to indicate a fileread, rather than
|
|
|
+ reading a string from stdin
