One thing we must remember is the report sub command only supports one kind of resource, not multiples.

docker run -it -e AWS_ACCESS_KEY_ID="XXX" -e AWS_SECRET_ACCESS_KEY="XXX"  -e AWS_DEFAULT_REGION="eu-west-1"    -v $(pwd)/output:/home/custodian/output  -v $(pwd)/tag.yml:/home/custodian/tag.yml    cloudcustodian/c7n report -v  -s /home/custodian/output /home/custodian/tag.yml --format grid

Here we can see there are at least 125 EC2 which are no compliance based on the policy we already have wroted

2020-09-02 06:34:39,307: custodian.cache:DEBUG Disabling cache
2020-09-02 06:34:39,307: custodian.commands:DEBUG Loaded file /home/custodian/tag.yml. Contains 1 policies
2020-09-02 06:34:39,315: custodian.aws:DEBUG using default region:eu-west-1 from boto
2020-09-02 06:34:39,922: custodian.reports:DEBUG Found 125 records for region eu-west-1
2020-09-02 06:34:39,923: custodian.reports:DEBUG Uniqued from 125 to 125

Command will return a grid using the --format grid option
