我正在嘗試在 SLES 12.5 上安裝 docker。我試圖按照這個 SO answer上的說明進行操作。

初步嘗試

# zypper addrepo https://download.opensuse.org/repositories/Virtualization:containers/SLE_12_SP5/Virtualization:containers.repo
Adding repository 'Virtualization:containers (SLE_12_SP5)' ...........................................................................................................[done]

Enabled     : Yes
GPG Check   : Yes
Autorefresh : No
Priority    : 99 (default priority)

Repository priorities are without effect. All enabled repositories share the same priority.

# zypper refresh

第二次嘗試

我在 Unix & Linux 上發現這個問題有類似的錯誤，所以我編輯了/etc/zypp/repos.d/Virtualization_containers.repo文件如下：

前：

[Virtualization_containers]
name=Virtualization:containers (SLE_12_SP5)
enabled=1
autorefresh=0
baseurl=https://download.opensuse.org/repositories/Virtualization:/containers/SLE_12_SP5/
type=rpm-md
gpgcheck=1
gpgkey=https://download.opensuse.org/repositories/Virtualization:/containers/SLE_12_SP5/repodata/repomd.xml.key

後：

[Virtualization_containers]
name=Virtualization:containers (SLE_12_SP5)
enabled=1
autorefresh=0
baseurl=http://download.opensuse.org/repositories/Virtualization:/containers/SLE_12_SP5/
type=rpm-md

然後又試了一次：

# zypper refresh
Repository 'SLES12-SP5-Pool' is up to date.
Repository 'SLES12-SP5-Updates' is up to date.
Repository 'Update' is up to date.

第三次嘗試

我試圖放棄zypper並使用另一種安裝方法。我在這裡找到了一個 RPM 文件

https://download.opensuse.org/repositories/Virtualization:/containers/SLE_12_SP5/x86_64/docker-19.03.12_ce-378.39.x86_64.rpm

問題

那麼如何在 SLES 12.5 上安裝 Docker？我可以修Redirect to protocol "http" not supported or disabled in libcurl嗎？

在這。

嘗試 2 應該有效，但該特定 URL ( http://download.opensuse.org/repositories/Virtualization:/containers/SLE_12_SP5/repodata/a02bda6c6525d5d550e34e98844bf0e18a66aa1a24282c72a80c4679ef2e121d-primary.xml.gz) 被自動重定向到各種 opensuse 儲存庫鏡像之一。我通過嘗試直接下載它來解決它wget，它顯示了重定向。由於網路連接允許列表中不包含此特定鏡像，因此無法訪問該鏡像（因此超時）。解決方法是將此鏡像包含在允許列表中。
