I know that there is a lot of content available for this, but none of them gave me what I desired the most.
I wanted to push my latest commit to the newly created tag on my Git Repo. I referred this:
Now, after reading, I knew that, that what I need is git push origin <tagname>. Before that, I did
$ git <tagname>
$ git show <tagname>
Both of them showed me the correct result, which gave me a green signal to go and implement the final command.
$ git add .
$ git commit -am "My message"
$ git push origin <tagname>
Now, when I did git push origin <tagname>, I got this Everything up-to-date. I saw my GIT Repo, and nothing was pushed. After looking at some of the answers, I finally found something which worked for me partially, that is
$ git push origin : <tagname>
This indeed pushed my data to the repo, but when I checked my Tag, it did not reflect in it, it showed my the last commit only, not the current one, which I pushed just now. How can I do that, so that I can achieve pushing my data to a particular tag successfully?
A tag does not get updated with actions such as git commit.
Taking the steps from your question and numbering them :
1. git tag <tagname>
2. git show <tagname>
3. git add .
4. git commit -am "My message"
5. git push origin <tagname>
The commit at step 4. have moved your active branch, it hasn't updated the tag created at step 1..
If you typed git show <tagname> again, the tag would still be at its starting place.
If you want to update the tag locally, you have to run :
git tag --force <tagname>
If you want to additionally push that tag to origin :
git push origin --force <tagname>
