Changes
→Version 1.0
There are three major versions of compose file format.
'''build''':<br>In version 1 file format, build is different in two ways:
* Only the string form (build: .) is allowed - not the object form that is allowed in Version 2 and up.
* Using build together with image is not allowed. Attempting to do so results in an error.
'''dockerfile''': Dockerfile-alternate
'''command''': Override the default command.
<pre>
command: ["bundle", "exec", "thin", "-p", "3000"]
</pre>
'''container_name''': Specify a custom container name, rather than a generated default name
'''dns''': Custom DNS servers. Can be a single value or a list.
<pre>
dns: 8.8.8.8
dns:
- 8.8.8.8
- 9.9.9.9
</pre>
