[BUG] Docker container html template is not compatible with generator

[DenisNovac]

Describe the bug.

I am using docker container https://hub.docker.com/r/asyncapi/generator , version 2.0.3

It is downloading latest (2.3.9) html-template automatically:

asyncapi-generator -i doc/input.yml -o doc/generated @asyncapi/html-template -p singleFile=true -p outFilename=out.html --force-write --debug

Warning: Ignoring extra certs from `/usr/local/share/ca-certificates/squid-ca-cert.crt`, load failed: error:02001002:system library:fopen:No such file or directory
Template installation started because you passed --install flag.
(node:43) Warning: Setting the NODE_TLS_REJECT_UNAUTHORIZED environment variable to '0' makes TLS connections and HTTPS requests insecure by disabling certificate verification.

Something went wrong:

There is no newer versions neither for html-template nor for generator.

However, when i do the same in local CLI for the same file - it works:

asyncapi config versions

Hey there, sorry for late response - vacation and some other harder moments in life 😄

It is downloading latest (2.3.9) html-template automatically

what do you mean? docker image with generator do not contain html-template.
when you run asyncapi-generator -i doc/input.yml -o doc/generated @asyncapi/html-template -p singleFile=true -p outFilename=out.html --force-write --debug the generator downloads template on the fly, with latest version as @asyncapi/html-template means latest -> have a read of https://www.asyncapi.com/docs/tools/generator/versioning

asyncapi generate fromTemplate in.yml @asyncapi/html-template -o ./docs --force-write --debug

yes, this works, cause if you look into the output of asyncapi config versions the version of generator in the CLI is older than v2. html-template is not yet on v2. We need to get asyncapi/cli#1388 done first.

I definitely discourage you from using the docker image provided by generator, with Generator CLI because we will anyway set it to deprecation -> #1212. You probably noticed that in generator docs we do not even talk about Generator CLI anymore

does that help?

[DenisNovac]

Thank you for answering!

html-template is not yet on v2

I guess, this explains my problem.
Long story short - our CI upgraded the container to v2 and started to fail at some point. I just downgraded it and now it works. Maybe next time we will update it when v2 is supported.
