はじめに
目を離していたらCodeReady Containersが 1.7から1.11に(笑)
ということでまずは環境をアップデートします。
- OS: CentOS7 with GNOME Desktop
- CodeReady Containers 1.7 → 1.11
ちなみにCodeReady Container 1.11はOpenShift 4.4.5だそうです。
まずはマニュアルを確認
2.4. Upgrading CodeReady Containers
既にProjectがありPodがある場合、YAMLやコマンドから再作成できるようにしておいてください。
CodeReady Containerを一度削除するため、消えてしまいます。
1. Download the latest release of CodeReady Containers.
RedhatのDLページより最新のCodeReady ContainerをDLします。
Code Ready Containers
[tak@minishift4 ~]$ cd /tmp
[tak@minishift4 tmp]$ curl -S https://mirror.openshift.com/pub/openshift-v4/clients/crc/latest/crc-linux-amd64.tar.xz -o /tmp/crc-linux-amd64.tar.xz
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 2078M 100 2078M 0 0 14.0M 0 0:02:27 0:02:27 --:--:-- 14.4M
ダウンロード出来たら解凍します。
[tak@minishift4 tmp]$ xz -dc /tmp/crc-linux-amd64.tar.xz | tar xfv -
crc-linux-1.11.0-amd64/
crc-linux-1.11.0-amd64/LICENSE
crc-linux-1.11.0-amd64/doc.pdf
crc-linux-1.11.0-amd64/crc
ここでバージョン念のため確認してみましょう。
今のバージョン
OpenShiftは4.3.1
[tak@minishift4 tmp]$ crc version
crc version: 1.7.0+fa7e558
OpenShift version: 4.3.1 (embedded in binary)
ダウンロードしてきたCodeReady Containerのバージョン
OpenShift4.4.5となっていますね。
[tak@minishift4 tmp]$ cd crc-linux-1.11.0-amd64/
[tak@minishift4 crc-linux-1.11.0-amd64]$ ./crc version
crc version: 1.11.0+883ca49
OpenShift version: 4.4.5 (embedded in binary)
2. Delete the existing CodeReady Containers virtual machine:
WARNING
The crc delete command results in the loss of data stored in the CodeReady Containers virtual machine. Save any desired information stored in the virtual machine before running this command.
今現状は環境整備しただけなのでわたしは構わず消しちゃいます。
[tak@minishift4 tmp]$ cd ~
[tak@minishift4 ~]$ crc delete
Do you want to delete the OpenShift cluster? [y/N]: y
Deleted the OpenShift cluster
3. Replace the earlier crc binary with the binary of the latest release. Verify that the new crc binary is in use by checking its version:
今のcrcの場所を確認し置き換えます。
わたしはファイルに権限与えていますが、権限がない場合はsudoしてください。
[tak@minishift4 ~]$ which crc
/usr/local/bin/crc
[tak@minishift4 ~]$ cd /tmp
[tak@minishift4 tmp]$ cd crc-linux-1.11.0-amd64/
[tak@minishift4 crc-linux-1.11.0-amd64]$ ls
LICENSE crc doc.pdf
[tak@minishift4 crc-linux-1.11.0-amd64]$ cp -p crc /usr/local/bin/
バージョン確認を行います。
[tak@minishift4 crc-linux-1.11.0-amd64]$ cd ~
[tak@minishift4 ~]$ crc version
crc version: 1.11.0+883ca49
OpenShift version: 4.4.5 (embedded in binary)
はい。大丈夫ですね！
4. Set up the new CodeReady Containers release:
CodeReady Containerのセットアップを行います。
途中でsudoするのにパスワードが聞かれます。

Setup is complete, you can now run 'crc start' to start the OpenShift cluster
5. Start the new CodeReady Containers virtual machine:
さていよいよ起動です。
起動初回は「Image pull secret」を聞かれますのでダウンロードまたはクリップボードにCopyしておきます。
Pull Secretはダウンロードページ(Code Ready Containers)下部にあります。

INFO Then you can access it by running 'oc login -u developer -p developer https://api.crc.testing:6443'
INFO To login as an admin, run 'oc login -u kubeadmin -p 8rynV-SeYLc-h8Ij7-YPYcz https://api.crc.testing:6443'

INFO You can now run 'crc console' and use these credentials to access the OpenShift web console
Started the OpenShift cluster
WARN The cluster might report a degraded or error state. This is expected since several operators have been disabled to lower the resource usage. For more information, please consult the documentation
[tak@minishift4 ~]$
ちょっとWARNでちゃいましたけど…汗
WebConsoleの確認
Web Consoleにアクセスします。
[tak@minishift4 ~]$ crc console
Opening the OpenShift Web Console in the default browser...
This tool has been deprecated, use 'gio open' instead.
See 'gio help open' for more info.
ちょっとイメージが変わりましたね。
ご対面～っと思ったらWeb Console死んじゃいました(笑)
もう一度時間をおいてアクセス！
とりあえずこれで環境構築は完了です。
YAML勉強しなきゃー汗
