昨夜～今朝でストレージ不足で成功しなかったRed Hat CodeReady ContainersでローカルOpenShift 4にチャレンジ。
必要なのはRed Hatの開発者アカウント(無料)
細かい手順は失敗編のこちら zaki-hmkc.hatenablog.com
VMの準備(主にストレージ)

よし、やるぞ。
手順おさらい
バイナリのダウンロードとPATH設定
$ curl -LO https://mirror.openshift.com/pub/openshift-v4/clients/crc/1.0.0-rc.0/crc-linux-amd64.tar.xz $ sudo tar xf crc-linux-amd64.tar.xz -C /usr/local/ $ sudo ln -s /usr/local/crc-linux-1.0.0-rc.0-amd64/crc /usr/local/bin/ $ crc version
実行例
[zaki@codeready ~]$ crc version version: 1.0.0-rc.0+34371d3 OpenShift version: 4.2.0-0.nightly-2019-09-26-192831 (embedded in binary)
設定ファイルも勝手に作成される
[zaki@codeready ~]$ ls .crc/ crc.json crc.log
必要ソフトウェア
$ rpm -qa | grep NetworkManager $ rpm -qa | grep libvirt
NetworkManagerは最初から入ってるはず。
libvirtは入っていなくても次のCodeReadyのセットアップでinstallされるので大丈夫。
おそらくNetworkManagerも入ってなければinstallされそう。
CodeReadyのセットアップ
$ crc setup
こんな感じ

やった！ばんざーい！
[zaki@codeready ~]$ ls -a . .bash_history .bash_profile .crc .kube .. .bash_logout .bashrc crc-linux-amd64.tar.xz .pki [zaki@codeready ~]$ ls .kube/ cache http-cache [zaki@codeready ~]$
.kube/はあるけどconfigはないね。
ちなみにストレージ使用状態
[zaki@codeready ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/centos-root 76G 39G 37G 52% / devtmpfs 3.9G 0 3.9G 0% /dev tmpfs 3.9G 0 3.9G 0% /dev/shm tmpfs 3.9G 9.0M 3.9G 1% /run tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup /dev/sda1 1014M 142M 873M 14% /boot tmpfs 783M 0 783M 0% /run/user/1000
35GBじゃ足りなかった！！
OpenShiftクラスタの状態
ocコマンド
[zaki@codeready ~]$ ls .crc/bin/ crc-driver-libvirt oc [zaki@codeready ~]$
ocコマンドはここにあった。
というか(minishift使ったことあったらわかるやつだけど)crc startの出力にcrc oc-envとあるので、これを叩くとocの場所が分かるようになってる。
[zaki@codeready ~]$ crc oc-env export PATH="/home/zaki/.crc/bin:$PATH" # Run this command to configure your shell: # eval $(crc oc-env)
つまり
[zaki@codeready ~]$ eval $(crc oc-env) [zaki@codeready ~]$ which oc ~/.crc/bin/oc [zaki@codeready ~]$ [zaki@codeready ~]$ oc version Client Version: v4.3.0
oc login
oc loginのアクセス先サーバは、crc startの最後に出力されてるので、その通り実行すればOK
[zaki@codeready ~]$ oc login -u developer -p developer https://api.crc.testing:6443

You don't have any projects. You can try to create a new project, by running
oc new-project <projectname>
Welcome! See 'oc help' to get started.
[zaki@codeready ~]$
[zaki@codeready ~]$ oc whoami

[zaki@codeready ~]$ oc get pod --all-namespaces Error from server (Forbidden): pods is forbidden: User "developer" cannot list resource "pods" in API group "" at the cluster scope
なるほど。
admin権限でoc login
これもoc startの出力の内容を確認してログイン(パスワードも出力されてる)

お、minishiftにはなかったjboss-webserver50-tomcat9-openshiftとか入ってるのね。
CodeReady Containersを停止する
[zaki@codeready ~]$ crc stop Stopping CodeReady Containers instance... this may take a few minutes CodeReady Containers instance stopped [zaki@codeready ~]$
crc startのオプション、--vm-driver virtualboxとかあるしwin10homeでも動くのかな…？(未確認)
Appendix
DNSサーバの話
ちなみに、CodeReady Containersを入れるとローカルにDnsmasqが入る。
[zaki@codeready ~]$ rpm -qa | grep dnsm dnsmasq-2.76-9.el7.x86_64 [zaki@codeready ~]$ cat /etc/resolv.conf # Generated by NetworkManager search ocp4.localhost nameserver 127.0.0.1 [zaki@codeready ~]$
この辺はOpenShift ver3(Enterprise)とも同じかな。 試してはないけど、既にDNSサーバが動いているホスト上ではインストールできないかも。
仮想化の機能が不十分の場合のエラー
ホストOS上で仮想化機能が使えるように設定されてないとcrc startでエラーになる。

ESXiの場合は、VMの設定だけでなくESXi上でも仮想化機能を有効にする設定が必要
[root@localhost:~] cat /etc/vmware/config libdir = "/usr/lib/vmware" authd.proxy.nfc = "vmware-hostd:ha-nfc" authd.proxy.nfcssl = "vmware-hostd:ha-nfcssl" authd.proxy.vpxa-nfcssl = "vmware-vpxa:vpxa-nfcssl" authd.proxy.vpxa-nfc = "vmware-vpxa:vpxa-nfc" authd.fullpath = "/sbin/authd" vhv.enable = TRUE [root@localhost:~] [root@localhost:~] /etc/init.d/hostd restart watchdog-hostd: Terminating watchdog process with PID 69884 hostd stopped. hostd started. [root@localhost:~]
これでVMを再起動して再度crc startすればOK
参考: vSphere ESXi 上の仮想マシンで VT-x を有効化するには - らくがきちょう
