is hexo belongs to hexo?

I don't know about this. cc @NoahDragon

[bestony]

if no one have the hexo organization, I create a hexojs organization, I can push to this organ namespace

@bestony I have realized something: wrap hexo in hexod looks simpler, but npm will become inaccessible. Maybe another wrapper npmd for npm as well?

[bestony]

It's ok, But it must have to file to link docker command.
maybe add an alias to hexod is better?
just like

Hexod init  -> hexo init
hexod npm install -> npm install 

it maybe better than npmd ?

[SukkaW]

@bestony Agree, LGTM.

[bestony]

ok, I will try to add this feature

IMHO, we should close this PR and create a new repo then.

Dockerfile is no need to be published to npm. So it is unnecessary to have it in the repo. Also, Docker image is built with npm install instead of relying pm any files under hexojs/hexo.

@bestony What about creating a new GitHub repo hexo-docker and then transfer it to hexojs org then?

[bestony]

good idea. i will create a new repo,and try to transfer to hexojs

[bestony]

@SukkaW @curbengh Hi, I create a new repo for this pr, and i want to transfer it to hexojs. but alert "You don’t have the permission to create public repositories on hexojs".

so, what should i do next ?

My repo is here -> https://github.com/bestony/hexo-docker

[bestony]

and i add github action to automate publish docker images, and now ,you can download images by docker run hexojs/hexojs

https://hub.docker.com/repository/docker/hexojs/hexojs

[SukkaW]

@NoahDragon Would you please add @bestony to Hexo's plugin team? So he could transfer his repo to @hexojs's org.

[bestony]

any one can check this issue.
