This Docker provides preconfigured environment for running the command\n\
line REST client for $(tput setaf 6){{appName}}$(tput sgr0).\n\
\n\
For convenience, you can export the following environment variables:\n\
\n\
{{#x-codegen-host-env}}$(tput setaf 3){{x-codegen-host-env}}$(tput sgr0) - server URL, e.g. https://example.com:8080\n\{{/x-codegen-host-env}}
{{#hasAuthMethods}}
{{#authMethods}}
{{#isBasicBasic}}
{{#x-codegen-basicauth-env}}$(tput setaf 3){{x-codegen-basicauth-env}}$(tput sgr0) - basic authentication credentials, e.g.: "username:password"\n\{{/x-codegen-basicauth-env}}
{{/isBasicBasic}}
{{#isApiKey}}
{{#x-codegen-apikey-env}}$(tput setaf 3){{x-codegen-apikey-env}}$(tput sgr0) - access token, e.g. "ASDASHJDG63456asdASSD"\n\{{/x-codegen-apikey-env}}
{{/isApiKey}}
{{/authMethods}}
{{/hasAuthMethods}}
\n\
$(tput setaf 7)Basic usage:$(tput sgr0)\n\
\n\
$(tput setaf 3)Print the list of operations available on the service$(tput sgr0)\n\
$ {{x-codegen-script-name}} -h\n\
\n\
$(tput setaf 3)Print the service description$(tput sgr0)\n\
$ {{x-codegen-script-name}} --about\n\
\n\
$(tput setaf 3)Print detailed information about specific operation$(tput sgr0)\n\
$ {{x-codegen-script-name}} -h\n\
\n\
By default you are logged into Zsh with full autocompletion for your REST API,\n\
but you can switch to Bash, where basic autocompletion is also supported.\n\
