"git checkout tag-name" vs "git reset --hard tag-name"
提问by Tower
I know that there are questions like this, but that's not what I'm asking.
我知道有这样的问题这样，但是这不是我在问什么。
I also know that:
我也知道：
git checkout tag-name:
git checkout tag-name：
- Detaches you from the branch. (i.e. moves
HEADpointer, keepsBRANCHpointer)
- 将您从分支中分离出来。（即移动
HEAD指针，保持BRANCH指针）
git reset --hard tag-name:
git reset --hard tag-name：
- Does not detach you from the branch, but makes the previous commits to become "dangling". (i.e. moves both
HEADandBRANCHpointers)
- 不会将您与分支分离，而是使之前的提交变得“悬空”。（即同时移动
HEAD和BRANCH指针）
I wonder which one makes more sense for updating to a tag, i.e. should a production be reseted or checked out. I know that a garbage collector may run, removing dangling commits, but then again, if the production is always "pulled" before the process of updating to a tag, I see nothing bad there.
我想知道哪一个更适合更新标签，即是否应该重置或检查产品。我知道垃圾收集器可能会运行，删除悬空的提交，但话又说回来，如果在更新到标签的过程之前总是“拉”生产，我认为那里没有什么不好的。
Should a production update to a tag with resetor checkout, considering that a pullis always done prior to this update call?
考虑到 a总是在此更新调用之前完成，是否应该使用reset或对标签进行生产更新？checkoutpull

我想知道哪一个更适合更新标签
Your production install should be checking out a tag.
您的生产安装应该检查标签。
Think of it this way: your production install is read-only. git reset --hard tag-namewill modify the currently checked out branch.
这样想：您的生产安装是只读的。git reset --hard tag-name将修改当前签出的分支。
Alternatively
或者
It's common practice that in addition to creating a tag, you have one branch which is simply the latest release. In which case you'd e.g. merge to master and create a tag from there; and on your production installs you'd update simply with git pull (on master).
通常的做法是，除了创建标签之外，您还有一个分支，它只是最新版本。在这种情况下，您可以合并到 master 并从那里创建一个标签；在您的生产安装中，您只需使用 git pull （在 master 上）进行更新。
