1. containerd安裝
[Ubuntu 22.04] 安裝containerd
2. 源碼編譯
??主要步驟如下：
- 1、從github下載
containerd源碼git clone git@github.com:containerd/containerd.git
- 2、切換到想要
debug的分支或者tag，我這里選擇切換到1.7.2版本的taggit branch v1.7.2 v1.7.2 && git checkout v1.7.2
- 3、下載
contaienrd的依賴cd containerd && go mod tidy
- 4、編譯

??注意，編譯的時候containerd會依賴btrfs文件系統(tǒng)，如果沒有安裝，編譯的時候會報錯（提示：linux/btrfs_tree.h: No such file or directory）。按照文檔第一步安裝containerd不會遇到這個問題。
3. 驗證編譯的二進制文件是否含有調試需要的信息
??注意，以下三種驗證方式，選擇其中的一種驗證成功即可。
3.1. objdump工具驗證
??正確的現(xiàn)象如下，執(zhí)行objdump --syms bin/containerd是可以看到調試信息的
root@containerd:~/workspace/containerd# objdump --syms bin/containerd
bin/containerd: file format elf64-x86-64

4. debug
??debug containerd步驟如下：
- 1、利用
ps -ef|gerp containerd查看containerd啟動所需要的參數(shù)，這一步特別重要，尤其是在debug k8s源碼的時候，k8s的每一個組件都帶了很多命令行參數(shù)，想要調試這些組件，必須把這些組件的啟動參數(shù)原封不動的加入到dlv調試命令當中- 注意，實際上執(zhí)行上述命令之后會發(fā)現(xiàn)，
containerd并沒有啟動參數(shù)，因此無需關心。
- 注意，實際上執(zhí)行上述命令之后會發(fā)現(xiàn)，
- 2、通過
dlv命令啟動containerd，啟動命令我們可以從IDEA remote debug功能拷貝過來dlv --listen=:12345 --headless=true --api-version=2 --accept-multiclient exec bin/containerd- 注意：這里在啟動
contaienrd的時候沒有指定任何參數(shù)，實際上也可以根據(jù)自己的情況加入containerd參數(shù)，譬如指定containerd的配置文件的位置（containerd默認配置文件為：/etc/containerd/config.toml），也可以指定調試的debug級別，譬如：dlv --listen=:12345 --headless=true --api-version=2 --accept-multiclient exec bin/containerd -- --config=/root/mycontainerd/config.toml --log-level=debug
- 3、在
IDEA啟動debug，連接到遠程調試- 注意：在啟動
IDEA調試之前，你需要在想要debug的位置增加斷點，否則程序啟動會直接運行起來，等你這個時候打斷點，很可能就晚了。 - 注意：在啟動
IDEA調試之前，你需要修改IDEA操作系統(tǒng)標識為Linux
- 注意：在啟動
