Flag -t (template directory) not workin in docker

[RussianDragon]

Hi.
I try create custom template, but having a problem with template folder.

For beginning i just copy template typescript-fetch and try use it my local folder.
docker run --rm -v C:\generatortest:/local openapitools/openapi-generator-cli:v5.4.0 generate -i /local/swagger_api.json -g typescript-custom -o /local/out/typescript8 --skip-validate-spec -t /local/template
In the console I see.

Can't load config class with name 'typescript-custom'

[error] Check the spelling of the generator's name and try again.

I don't understand why not working special template folder...
Problem persists on the latest version docker container.

Can't load config class with name 'typescript-custom'

looks like that's the issue. it can't find the generator "typescript-custom"

[adrianwix]

Unless you are implementing your own generator by extending the class you have to use the same typescript-axios generator but with another template

[RussianDragon]

I need create new specific generator.
But I don't find a simple guide.
On this page
There doesn't say how to set the templates directory. And "-t" doesn't work.

I don't understand how to run the test template created after the command:
meta -o out/generators/my-codegen -n my-codegen -p com.my.company.codegen

---

I use next command for generate:
docker run --rm -v C:\generatortest:/local openapitools/openapi-generator-cli:v6.2.1 generate
-i /local/swagger.json
-g my-codegen
-t /local/template
-o /local/out/typescript_2
