You can use this image just like the hexo-cli, for example:

docker run --rm davyyy/hexo help

The commands hexo init and npm install already ran when built the docker image, so you don't have to download anything to start.

docker run --name hexo-server -d -p YOURPORT:4000 -v /YOUR/BLOG/PATH/:/blog  davyyy/hexo server

Notes:

• name the container, because we will use it later in volumes-from.
• we start the server here, so run in background with -d option.
• choose a port you want to expose
• choose a local directory for your blogs

The /YOUR/BLOG/PATH/ shoud be empty(or not exists) when first run container from this image. If the directory is empty, it will copy all init files from the image to the volume, otherwise do nothing. And you can run hexo init command by yourself if you like, of course.

docker run --rm --volumes-from hexo-server davyyy/hexo new foo
INFO  Created: /blog/source/_posts/foo.md

Then you can write your post with your favorite editer, for example:

  vim /YOUR/BLOG/PATH/source/_posts/foo.md

Just remember:

• we don't need keep this container, so don't forget to use the --rm option to remove it automatically.
• use --volumes-from to mount from our earlier created blog volume, otherwise it will create a new volume with initial hexo.

docker run --rm --volumes-from hexo-server davyyy/hexo gen

docker run --rm --volumes-from hexo-server davyyy/hexo deploy
