Does ECS task definition support volume mapping syntax?
Yes, of course, ECS support docker socket mounting, but the syntax is bit different. Add DOCKER_HOST environment variable in the task definition and source path should start with //.
"volumes": [ { "name": "docker", "host": { "sourcePath": "//var/run/docker.sock" } } ]The // worked in case of AWS ecs.
Also, you need to add DOCKER_HOST environment variable in your task definition.
"environment": [ { "name": "DOCKER_HOST", "value": "unix:///var/run/docker.sock" } ]
