Sometimes a projects has a lot of secrets (more than 10). And its
cumbersome to write $(kama secrets fetch ...) with a lot of field
names.
I want to be able to just fetch all the fields from a given item
and then just use these with $(kamal extract NAME)
Dotenv's variable substitution doesn't work the same way as commands run
in the shell. It needs values to be escaped.
```sh
$ cat /tmp/env
SECRETS=$(cat /tmp/json)
SECRETS2=$(echo $SECRETS | jq)
$ cat /tmp/json
\{\ \"foo\"\ :\ \"bar\" \}
$ SECRETS=$(cat /tmp/json)
$ SECRETS2=$(echo $SECRETS | jq)
jq: parse error: Invalid numeric literal at line 1, column 2
$ ruby -e 'require "dotenv"; puts Dotenv.parse("/tmp/env")["SECRETS2"]'
{
"foo": "bar"
}
```
Since you then can't use the shell to debug, `kamal secrets print` will
allow you to see what the secrets will be set to.
When fetched item is not a login, Bitwarden adapter raises NoMethodError
because the returned JSON does not have the login.password value.
Add a nicer error message for that case.
Add commands for managing proxy boot config. Since the proxy can be
shared by multiple applications, the configuration doesn't belong in
`config/deploy.yml`.
Instead you can set the config with:
```
Usage:
kamal proxy boot_config <set|get|clear>
Options:
[--publish], [--no-publish], [--skip-publish] # Publish the proxy ports on the host
# Default: true
[--http-port=N] # HTTP port to publish on the host
# Default: 80
[--https-port=N] # HTTPS port to publish on the host
# Default: 443
[--docker-options=option=value option2=value2] # Docker options to pass to the proxy container
```
By default we boot the proxy with `--publish 80:80 --publish 443:443`.
You can stop it from publishing ports, specify different ports and pass
other docker options.
The config is stored in `.kamal/proxy/options` as arguments to be passed
verbatim to docker run.
Where someone wants to set the options in their application they can do
that by calling `kamal proxy boot_config set` in a pre-deploy hook.
There's an example in the integration tests showing how to use this to
front kamal-proxy with Traefik, using an accessory.
