fix: container binds syntax

The container binds syntax is `host-src:container-dest[:options]` or
`volume-name:container-dest[:options]` where `options` is a comma
separated list of: `nocopy` `[ro|rw]`, `[z|Z]` or
`[[r]shared|[r]slave|[r]private]`. See `HostConfig.Binds` of the Create
a container request[1]
