整理的常用 Git 命令清单。几个专用名词的译名如下。
Workspace：工作区
Index / Stage：暂存区
Repository：仓库区（或本地仓库）
Remote：远程仓库
当你修复完线上问题，切回 feature 分支，想恢复代码也只需要：git stash apply
相关命令# 保存当前未commit的代码
git stash
# 保存当前未commit的代码并添加备注
git stash save "备注的内容"
# 列出stash的所有记录
git stash list
# 删除stash的所有记录
git stash clear
# 应用最近一次的stash
git stash apply
# 应用最近一次的stash，随后删除该记录
git stash pop
# 删除最近的一次stash
git stash drop
一、新建代码库
在当前目录新建一个Git代码库 $ git init
新建一个目录，将其初始化为Git代码库 $ git init [project-name]
下载一个项目和它的整个代码历史 $ git clone [url]
二、配置
Git的设置文件为.gitconfig，它可以在用户主目录下（全局配置），也可以在项目目录下（项目配置）。
#显示当前的Git配置 $ git config --list
#编辑Git配置文件 $ git config -e [–global]
#设置提交代码时的用户信息 $ git config [–global] user.name “[name]”
$ git config [–global] user.email “[email address]”
三、增加/删除文件
#添加指定文件到暂存区 $ git add [file1] [file2] …
#添加指定目录到暂存区，包括子目录 $ git add [dir]
#添加当前目录的所有文件到暂存区 $ git add .
#添加每个变化前，都会要求确认 # 对于同一个文件的多处变化，可以实现分次提交 $ git add -p
#删除工作区文件，并且将这次删除放入暂存区 $ git rm [file1] [file2] …
#停止追踪指定文件，但该文件会保留在工作区 $ git rm --cached [file]
#改名文件，并且将这个改名放入暂存区 $ git mv [file-original] [file-renamed]
四、代码提交
#提交暂存区到仓库区 $ git commit -m [message]
#提交暂存区的指定文件到仓库区 $ git commit [file1] [file2] … -m [message]
#提交工作区自上次commit之后的变化，直接到仓库区 $ git commit -a
#提交时显示所有diff信息 $ git commit -v
#使用一次新的commit，替代上一次提交 # 如果代码没有任何新变化，则用来改写上一次commit的提交信息 $ git commit --amend -m [message]
#重做上一次commit，并包括指定文件的新变化 $ git commit --amend [file1] [file2] …
五、分支
#列出所有本地分支 $ git branch
#列出所有远程分支 $ git branch -r
#列出所有本地分支和远程分支 $ git branch -a
#新建一个分支，但依然停留在当前分支 $ git branch [branch-name]
#新建一个分支，并切换到该分支 $ git checkout -b [branch]
#新建一个分支，指向指定commit $ git branch [branch] [commit]
#新建一个分支，与指定的远程分支建立追踪关系 $ git branch --track [branch] [remote-branch]
#切换到指定分支，并更新工作区 $ git checkout [branch-name]
#切换到上一个分支 $ git checkout -
#建立追踪关系，在现有分支与指定的远程分支之间 $ git branch --set-upstream [branch] [remote-branch]
#合并指定分支到当前分支 $ git merge [branch]
#选择一个commit，合并进当前分支 $ git cherry-pick [commit]
#删除分支 $ git branch -d [branch-name]
#删除远程分支 $ git push origin --delete [branch-name]
$ git branch -dr [remote/branch]
六、标签
#列出所有tag $ git tag
#新建一个tag在当前commit $ git tag [tag]
#新建一个tag在指定commit $ git tag [tag] [commit]
#删除本地tag $ git tag -d [tag]
#删除远程tag $ git push origin :refs/tags/[tagName]
#查看tag信息 $ git show [tag]
#提交指定tag $ git push [remote] [tag]
#提交所有tag $ git push [remote] --tags
#新建一个分支，指向某个tag $ git checkout -b [branch] [tag]
git tag -a 2020-07-08 -m '2020-07-08'
git push 2020-07-08
七、查看信息
#显示有变更的文件 $ git status
#显示当前分支的版本历史 $ git log
#显示commit历史，以及每次commit发生变更的文件 $ git log --stat
#搜索提交历史，根据关键词 $ git log -S [keyword]
#显示某个commit之后的所有变动，每个commit占据一行 $ git log [tag] HEAD --pretty=format:%s
#显示某个commit之后的所有变动，其"提交说明"必须符合搜索条件 $ git log [tag] HEAD --grep feature
#显示某个文件的版本历史，包括文件改名 $ git log --follow [file]
$ git whatchanged [file]
#显示指定文件相关的每一次diff $ git log -p [file]
#显示过去5次提交 $ git log -5 --pretty --oneline
#显示所有提交过的用户，按提交次数排序 $ git shortlog -sn
#显示指定文件是什么人在什么时间修改过 $ git blame [file]
#显示暂存区和工作区的差异 $ git diff
#显示暂存区和上一个commit的差异 $ git diff --cached [file]
#显示工作区与当前分支最新commit之间的差异 $ git diff HEAD
#显示两次提交之间的差异 $ git diff [first-branch]…[second-branch]
#显示今天你写了多少行代码 $ git diff --shortstat “@{0 day ago}”
#显示某次提交的元数据和内容变化 $ git show [commit]
#显示某次提交发生变化的文件 $ git show --name-only [commit]
#显示某次提交时，某个文件的内容 $ git show [commit]:[filename]
#显示当前分支的最近几次提交 $ git reflog
八、远程同步
#下载远程仓库的所有变动 $ git fetch [remote]
#显示所有远程仓库 $ git remote -v
#显示某个远程仓库的信息 $ git remote show [remote]
#增加一个新的远程仓库，并命名 $ git remote add [shortname] [url]
#取回远程仓库的变化，并与本地分支合并 $ git pull [remote] [branch]
#上传本地指定分支到远程仓库 $ git push [remote] [branch]
#强行推送当前分支到远程仓库，即使有冲突 $ git push [remote] --force
#推送所有分支到远程仓库 $ git push [remote] --all
九、撤销
#恢复暂存区的指定文件到工作区 $ git checkout [file]
#恢复某个commit的指定文件到暂存区和工作区 $ git checkout [commit] [file]
#恢复暂存区的所有文件到工作区 $ git checkout .
#重置暂存区的指定文件，与上一次commit保持一致，但工作区不变 $ git reset [file]
#重置暂存区与工作区，与上一次commit保持一致 $ git reset --hard
#重置当前分支的指针为指定commit，同时重置暂存区，但工作区不变 $ git reset [commit]
#重置当前分支的HEAD为指定commit，同时重置暂存区和工作区，与指定commit一致 $ git reset --hard [commit]
#重置当前HEAD为指定commit，但保持暂存区和工作区不变 $ git reset --keep [commit]
#新建一个commit，用来撤销指定commit # 后者的所有变化都将被前者抵消，并且应用到当前分支 $ git revert [commit]
#暂时将未提交的变化移除，稍后再移入 $ git stash
$ git stash pop
十、其他
#查看远程分支和本地分支的对应关系 $git remote show origin
#从本地删除远程已经删除的分支的tracking(在issue被merge之后，远程分支会被删除，那么相应的本地tracking我们也可以删除掉) $git remote prune origin
#从本地删除远程已经删除的分支（merge后可以执行此操作保持工作区的清洁） $git fetch -p && for branch in `git branch -vv | grep ': gone]' | awk '{print $1}'`; do git branch -D $branch; done
#生成一个可供发布的压缩包 $ git archive
st #字符串加解密 $SALT 是盐字符串,作为 gitlab-ci 全局变量,只有管理员知道
#加密: echo $(cat ./config | base64) |tr -d " "|openssl aes-256-cbc -salt -pbkdf2 -k $SALT > secret_kubeconfig

${VALUE:=WORD}：当变量未定义或者值为空时，返回WORD的值的同时并将WORD赋值给VALUE，否则返回变量的值。
${VALUE:+WORD}：当变量已赋值时，其值才用WORD替换，否则不进行任何替换。
${VALUE:?MESSAGE}：当变量已赋值时，正常替换。否则将消息MESSAGE送到标准错误输出（若此替换出现在SHELL程序中，那么该程序将终止运行）。
补充：WORD可以为一个字符串，也可以为一个变量。当为变量时，需要用“$”引用该变量。

1.当将线上kubernetes宿主机的ARP参数都改大后，再也没有出现过此类问题了。
sysctl -w net.ipv4.neigh.default.gc_thresh3=32768

2.K8S故障排查指南- but volume paths are still present on disk
1.上面错误信息可以通过 journalctl -u kubelet -f 或者 tail -f /var/log/messages 命令查看到。
2. # 查看 etc-hosts 文件中 pod name 名称
$ cat /var/lib/kubelet/pods/9e6d9bdd-1554-45e6-8831-53e83f8ea263/etc-hosts
# 删除 9e6d9bdd-1554-45e6-8831-53e83f8ea263 目录
$ cd /var/lib/kubelet/pods/
$ rm -rf 9e6d9bdd-1554-45e6-8831-53e83f8ea263
3. 现在在通过 journalctl -u kubelet -f 命令看kubelet日志，就没有 Orphaned pod found - but volume paths are still present on disk 报错了。
3.走flannel的vxlan网络，vxlan需要放开udp/8472
4. 下面配置意味着单个负载会调度到一个剩余CPU request大于0.1核，剩余request内存大于200MB的节点，并且负载运行时的CPU使用率不能高于0.4核（超过将被限流），内存使用不多余300MB（超过将被OOM Kill并重启）
resources:
requests:
memory: 200Mi
cpu: "0.1"
limits:
memory: 300Mi
cpu: "0.4"
5. 使用 kubectl 来创建 TLS Secret 时，你可以像下面的例子一样使用 tls 子命令：
kubectl create secret tls my-tls-secret --cert=path/to/cert/file --key=path/to/key/file
# 镜像字体 fonts-dejavu
# /etc/sysctl.d/k8s.conf ( 确保 pod 之间 IP 互通)
net.bridge.bridge-nf-call-ip6tables = 1
net.ipv4.ip_forward = 1
net.bridge.bridge-nf-call-iptables = 1
6. kubectl get pod --field-selector=status.phase==Running
7. immutable: true ( 不可更改的 secret / configmap )
8. 访问某pod的某个容器: kubectl --namespace=default exec -it user-deployment-54469dd57-vg87g --container user -- sh
# kubectl scale deploy -n --replicas=1 --all 可以用用scale指令修改指定命名空间下所有的deploy的副本数量。
#设置k8s预留资源保护
#/etc/systemd/system/kubelet.service.d/10-kubeadm.conf
#Environment="KUBELET_CUSTOMIZED_ARGS1=--eviction-hard=imagefs.available<15%,memory.available<2Gi,nodefs.available<10%,nodefs.inodesFree<5% --system-reserved=memory=1Gi --kube-reserved=memory=400Mi --kube-reserved=pid=1000 --system-reserved=pid=1000"
# systemctl daemon-reload;systemctl restart kubelet (重启kubelet 生效)
#ingress配置增加注解（annotations）：nginx.ingress.kubernetes.io/ssl-redirect: 'true' 就可以实现http强制跳转至https
#deployment
imagePullPolicy: IfNotPresent
1.简述Kubernetes中Pod可能位于的状态？
Pending：API Server已经创建该Pod，且Pod内还有一个或多个容器的镜像没有创建，包括正在下载镜像的过程。
Running：Pod内所有容器均已创建，且至少有一个容器处于运行状态、正在启动状态或正在重启状态。
Succeeded：Pod内所有容器均成功执行退出，且不会重启。
Failed：Pod内所有容器均已退出，但至少有一个容器退出为失败状态。
Unknown：由于某种原因无法获取该Pod状态，可能由于网络通信不畅导致。
