vagrant up 오류 문의

해당 에러 케이스를 검색해보니, 사내 네트워크 일 경우 인증 에러들이 많이 발생하는 것 같은데

현재 사내 네트워크 사용 중 일까요?

일단 해당 이미지는 정상적으로 올라가져 있는건 확인했습니다.

한번 아래 명령어로 삭제 하시고, 다시 만들어 보시겠어요?

# 삭제
kubectl delete -f https://raw.githubusercontent.com/kubetm/kubetm.github.io/master/yamls/k8s-install/calico.yaml
kubectl delete -f https://raw.githubusercontent.com/kubetm/kubetm.github.io/master/yamls/k8s-install/calico-custom.yaml

# 생성
kubectl create -f https://raw.githubusercontent.com/kubetm/kubetm.github.io/master/yamls/k8s-install/calico.yaml
kubectl create -f https://raw.githubusercontent.com/kubetm/kubetm.github.io/master/yamls/k8s-install/calico-custom.yaml

그래도 안되면 kubectl get pods -A -o wide 명령을 날려보면 해당 Pod가 어느 노드에 생기는지 확인이 됩니다. 아마 Master Node 일 가능성이 높긴한데, 해당 노드에서 아래 명령으로 직접 이미지를 다운 받아 보세요.

docker pull quay.io/tigera/operator:v1.29.0

감사합니다.

정확히 어느 조치로 해결이 된건지 모르겠지만 vm설치해서 3대 모두 부팅 및 접속까지 확인했습니다.

위에 링크 댓글 중 인증서를 강제로 넣었다는 글이 있어서 그대로 했구요. plugin 설치 시 https를 http로 고치니 인증서 에러는 발생했지만 plugin 설치는 됐습니다.

그리고 Vagrantfile 파일도 수정했습니다. 처음에는 vbguest plugin이 제대로 설치되지 않았는지 오류가 났었으나, plugin 설치된 후 vagrant up 명령이 실행됐습니다.

 curl -o "C:\HashiCorp\Vagrant\embedded\cacert.pem" https://curl.se/ca/cacert.pem
 vagrant plugin install --plugin-clean-sources --plugin-source http://rubygems.org vagrant-reload vagrant-vbguest winrm winrm-elevated

\k8s>vagrant plugin list
vagrant-reload (0.0.1, global)
vagrant-vbguest (0.31.0, global)

  config.vm.box = "centos/7"
  config.vm.synced_folder "./", "/vagrant", disabled: true
  config.vbguest.installer_options = { allow_kernel_upgrade: true }

네. k8s폴더를 지우고 재시도 해봤습니다.

시도하면 아래처럼 plugin 설치가 되지 않았습니다.

C:\Users\사용자\k8s>vagrant plugin install vagrant-vbguest
Installing the 'vagrant-vbguest' plugin. This can take a few minutes...
ERROR:  SSL verification error at depth 2: unable to get local issuer certificate (20)

Vagrant failed to load a configured plugin source. This can be caused
by a variety of issues including: transient connectivity issues, proxy
filtering rejecting access to a configured plugin source, or a configured
plugin source not responding correctly. Please review the error message
below to help resolve the issue:

  SSL_connect returned=1 errno=0 state=error: certificate verify failed (unable to get local issuer certificate) (https://rubygems.org/specs.4.8.gz)

그래서 구글링 해보니 인증 오류시

C:\HashiCorp\Vagrant\embedded\gems\2.2.18\gems\vagrant-2.2.18\plugins\commands\plugin\command\mixin_install_opts.rb 파일을 수정해보라고 되어있어서 아래처럼 수정했습니다.

module VagrantPlugins
  module CommandPlugin
    module Command
      module MixinInstallOpts
        def build_install_opts(o, options)
          options[:plugin_sources] = [
            "http://rubygems.org",
            "http://gems.hashicorp.com",
          ]

          o.on("--entry-point NAME", String,
               "The name of the entry point file for loading the plugin.") do |entry_point|
            options[:entry_point] = entry_point
          end

          o.on("--plugin-clean-sources",
            "Remove all plugin sources defined so far (including defaults)") do |clean|
            options[:plugin_sources] = [] if clean
          end

          o.on("--plugin-source PLUGIN_SOURCE", String,
               "Add a RubyGems repository source") do |plugin_source|
            options[:plugin_sources] << plugin_source
          end

          o.on("--plugin-version PLUGIN_VERSION", String,
               "Install a specific version of the plugin") do |plugin_version|
            options[:plugin_version] = plugin_version
          end
        end
      end
    end
  end
end

그 후 plugin 설치를 시도하면 아래처럼 설치가 됐습니다.
