Docker logs in JSON format. Log files are normally in
/var/lib/docker/containers/*/*-json.log, depending on what your Docker
data directory is.
Assuming following inputs are coming from a log file: df14e0d5ae4c07284fa636d739c8fc2e6b52bc344658de7d3f08c36a2e804115-json.log:
{
"log": "2015/05/05 19:54:41 \n",
"stream": "stderr",
"time": "2015-05-05T19:54:41.240447294Z"
}
Then output becomes as belows
{
"log": "2015/05/05 19:54:41 \n",
"stream": "stderr",
"docker": {
"id": "df14e0d5ae4c07284fa636d739c8fc2e6b52bc344658de7d3f08c36a2e804115",
