### Special handling for quoted values for TLS flags
**Deprecated in Release: v28.4**
**Target For Removal In Release: v29.0**
The `--tlscacert`, `--tlscert`, and `--tlskey` command-line flags had
non-standard behavior for handling values contained in quotes (`"` or `'`).
Normally, quotes are handled by the shell, for example, in the following
example, the shell takes care of handling quotes before passing the values
to the `docker` CLI:
```console
docker --some-option "some-value-in-quotes" ...
```
However, when passing values using an equal sign (`=`), this may not happen
and values may be handled including quotes;
```console
docker --some-option="some-value-in-quotes" ...
```
This caused issues with "Docker Machine", which used this format as part
of its `docker-machine config` output, and the CLI carried special, non-standard
handling for these flags.
Docker Machine reached EOL, and this special handling made the processing
of flag values inconsistent with other flags used, so this behavior is
deprecated. Users depending on this behavior are recommended to specify
the quoted values using a space between the flag and its value, as illustrated
above.
### Empty/nil fields in image Config from inspect API
**Deprecated in Release: v28.3**
