When attempting to build a local copy of the openapi files, I ran the .jenkins.sh script and received the following error: ``` Step 12/24 : RUN gem install asciidoctor-pdf-cjk ---> Running in ce3982ab7ed8 ERROR: Error installing asciidoctor-pdf-cjk: The last version of public_suffix (< 6.0, >= 2.0.2) to support your Ruby & RubyGems was 4.0.7. Try installing it with `gem install public_suffix -v 4.0.7` and then running the current command again public_suffix requires Ruby version >= 2.6. The current ruby version is 2.5.0. ``` This patch fixes the problem: ``` diff --git a/docker/Dockerfile b/docker/Dockerfile index b2bc215..38f0e96 100644 --- a/docker/Dockerfile +++ b/docker/Dockerfile @@ -13,6 +13,8 @@ RUN apk add openjdk8 RUN apk add ca-certificates wget && update-ca-certificates RUN apk add openssl RUN gem install rdoc -v 6.3.3 || gem install rdoc -v 6.3.3 +RUN gem install public_suffix -v 4.0.7 +RUN gem install css_parser -v 1.12.00 RUN gem install asciidoctor-pdf-cjk RUN wget https://forge.etsi.org/swagger2markup-cli-1.3.2.jar RUN npm config set proxy $http_proxy ```
