Security Group Port Changes

### Explanation:
When you modify the security group (e.g., adding a new port rule), the changes take effect immediately. AWS security groups are stateful, meaning any modifications (like adding or removing rules) are applied in real-time.

### To Verify:
1. **Check the Security Group Rules:**
– Go to the AWS Management Console.
– Navigate to **EC2** > **Security Groups**.
– Select the security group you modified.
– Ensure the new port rule is correctly listed under **Inbound rules**.

2. **Test the Connectivity:**
– Use a tool like `telnet`, `nc`, or `curl` from your local machine to verify that the port is accessible.
– Example:

# For HTTP-based services
     curl http://ec2-16-170-254-93.eu-north-1.compute.amazonaws.com:PORT_NUMBER
     
     # For SSH or other services
     telnet ec2-16-170-254-93.eu-north-1.compute.amazonaws.com PORT_NUMBER

If you still can't access the port, make sure:
– The EC2 instance's firewall (like `ufw` or `iptables`) allows traffic on that port.
– Any relevant service (like Nginx, Apache, or your Node.js app) is configured to listen on the new port.

curl: (7) Failed to connect to ec2-16-170-254-93.eu-north-1.compute.amazonaws.com port 3000 after 8 ms: Couldn't connect to server

It means that **the connection to the specified port is being blocked** or the service on that port is not running correctly. Here's how you can troubleshoot:

### 1. **Check Security Group Settings**
– Ensure that the security group attached to your EC2 instance allows inbound traffic on port `3000`.
– In the AWS Management Console, go to **EC2** > **Security Groups**.
– Select the security group and verify that there's a rule allowing inbound traffic on port `3000` from the IP addresses you're trying to connect from (or `0.0.0.0/0` for all IPs if you're testing publicly).

### 2. **Check Instance Firewall (e.g., UFW, iptables)**
– If you're using a firewall on your EC2 instance (e.g., `ufw` or `iptables`), make sure the firewall allows incoming traffic on port `3000`.
– To check `ufw` (if installed):

sudo ufw status

If necessary, allow traffic on port `3000`:

sudo ufw allow 3000/tcp

– For `iptables` (if used):

sudo iptables -L

If needed, add a rule to allow traffic on port `3000`:

sudo iptables -A INPUT -p tcp --dport 3000 -j ACCEPT

### 3. **Check if Service is Running**
– Ensure that the service you want to access (e.g., a web server or application on port 3000) is actually running and listening on the port.
– You can check this by running:

sudo netstat -tuln | grep 3000

You should see something like this if the service is running:

tcp        0      0 0.0.0.0:3000            0.0.0.0:*               LISTEN

– If it's not listed, the service may not be running, or it might not be configured to listen on port 3000. Restart the service or check its configuration.

### 4. **Check Service Logs**
– If the service (e.g., a Node.js app) isn't working as expected, check the logs for any errors. For example:

# For Node.js (if using pm2 or a similar service manager):
     pm2 logs your-app-name

### 5. **Check Nginx or Apache Config (if applicable)**
– If you're using a web server like Nginx or Apache to proxy requests to port 3000, ensure that the server is configured to forward traffic to that port.
– For Nginx, ensure that the `server` block in `/etc/nginx/nginx.conf` or `/etc/nginx/sites-available/default` has a proxy configuration for port 3000.

### 6. **Try Connecting from the EC2 Instance Itself**
– SSH into your EC2 instance and run:

curl http://localhost:3000

This will help you check if the service is accessible internally on the instance. If this works but external connections don't, the issue is likely with the security group, firewall, or service listening on the wrong interface.

By following these steps, you should be able to identify why the connection to port `3000` is failing.

### Here's what happens when you run `sudo ufw restart`:
1. **The firewall rules will be reloaded** – Any changes you've made to allow or block ports will take effect immediately.
2. **Active connections will not be disrupted** – UFW is designed to apply changes without interrupting ongoing network connections. However, be cautious if you’re making significant changes or configuring rules for remote access.

### Steps:
1. If you’ve just added the rule to allow traffic on port `3000`, you can run:

sudo ufw allow 3000/tcp

2. Restart UFW to apply any new rules:

sudo ufw restart

3. Check the status of UFW to ensure your rule is applied:

sudo ufw status

### Example Output:

To                         Action      From
--                         ------      ----
3000/tcp                   ALLOW       Anywhere
3000/tcp (v6)              ALLOW       Anywhere (v6)

Once UFW is restarted and the rule is applied, try accessing port `3000` again using `curl` or any other method from your local machine.

### Steps to Use `git pull –rebase`:
1. **Navigate to your local Git repository**:

cd /path/to/your/repo

2. **Run the rebase pull**:

git pull --rebase

This does the following:
– Fetches the latest changes from the remote repository (usually the `origin` remote).
– Rebases your local commits on top of the fetched changes.

### When to Use `git pull –rebase`:
– **Before pushing your changes**: If you've made commits locally and others have pushed changes to the remote repository, this command helps to incorporate those remote changes in a clean way before you push your commits.
– **To avoid merge commits**: If you want to maintain a linear history and avoid the creation of merge commits.

### Example Workflow:
1. You're working on a feature and have made a commit locally.
2. Meanwhile, someone else has pushed changes to the `main` branch on the remote repository.
3. To incorporate their changes into your local branch without creating a merge commit, you can run:

git pull --rebase

4. If there are conflicts during the rebase, Git will pause and allow you to resolve them. After resolving conflicts, you can continue the rebase with:

git rebase --continue

5. Once the rebase is complete and no conflicts remain, you can push your changes:

git push

### Notes:
– If you're working in a shared repository and others are also rebasing, make sure to communicate with your team to avoid rewriting history that others may be working on.
– If you're unsure about using rebase or need to preserve the original history, you might prefer `git pull` without the `–rebase` flag, which will create a merge commit instead.

### Steps to resolve the issue:

1. **Check the status of your repository**:
Run the following command to check the current state of the repository:

git status

This will tell you which files are in a conflicted state from the previous merge. Git will also indicate that a merge is in progress.

2. **Resolve the conflicts**:
– Open the conflicting files and resolve the conflicts manually. Conflicted areas are usually marked like this:

<<<<<<< HEAD
     Your changes here
     =======
     Changes from the branch you're merging
     >>>>>>> other-branch-name

– After resolving the conflicts, stage the changes:

git add <file1> <file2> ...

3. **Complete the merge**:
If you are done resolving conflicts, commit the merge:

git commit

If you were in the middle of a merge commit, this should finish the merge process.

4. **Start the rebase again**:
After resolving and committing the merge, you can safely attempt the rebase again:

git pull --rebase

If no further conflicts arise, the rebase will complete successfully.

### If you don't want to complete the merge and want to abort it:
If you're stuck in the middle of a merge and want to abort the merge process, use:

git merge --abort

This will reset your repository to the state before the merge started, allowing you to start over.

After aborting the merge, you can proceed with `git pull –rebase`.

### Summary:
– Resolve the current merge conflicts and commit the changes.
– If you're not ready to complete the merge, you can abort it with `git merge –abort`.
– After resolving the merge, proceed with `git pull –rebase`.

### To resolve this issue, follow these steps:

#### 1. **Pull the latest changes from the remote repository**
Since your branch is behind, you need to integrate the remote changes before you can push your own. If you're using `master` and want to rebase your changes on top of the remote changes, run:

git pull --rebase origin master

This fetches the changes from the remote `master` branch and applies your local changes on top of the remote changes.

– If there are conflicts, Git will pause and allow you to resolve them.
– After resolving conflicts, continue the rebase with:

git rebase --continue

#### 2. **Push your changes after the rebase**
Once you've successfully rebased your local branch on top of the remote `master`, push your changes:

git push origin master

Now, your push should be successful since you've integrated the remote changes first.

#### Alternative: **Merge Instead of Rebase**
If you don't want to use rebase, you can merge the remote changes into your local branch instead:
1. Run:

git pull origin master

2. Resolve any merge conflicts if necessary.

3. After the merge, push your changes:

git push origin master

### Important Notes:
– **Rebase vs. Merge**: Rebasing rewrites your local commit history to appear as if your commits were made after the remote commits, keeping the history cleaner. Merging creates a merge commit, which can result in a more complex history but keeps all commits intact.
– If you want to avoid conflicts or make the process easier, communicate with your team about the best strategy to handle pushing and pulling.

### Steps to resolve the issue:

#### 1. **Check the status of your repository:**
Run this command to see the current state of your repository and which files are in conflict:

git status

This will tell you which files are still in a conflicted state and need resolution.

#### 2. **Resolve any conflicts:**
If the `git status` shows conflicts, you need to open and resolve them manually. Conflicted files are marked in the following format:

<<<<<<< HEAD
Your changes
=======
Changes from the branch you're merging
>>>>>> other-branch-name

– Choose which changes to keep, or merge them appropriately.
– After resolving conflicts, stage the resolved files:

git add <file1> <file2> ...

#### 3. **Complete the merge:**
After resolving conflicts and staging the files, you can complete the merge by committing the changes:

git commit

Git may already have a default merge message for you. If you're satisfied with it, save and close the editor to commit.

#### 4. **Finish the merge and proceed with your work:**
Once the merge is complete, you should be able to run the previous commands, such as `git pull –rebase` or `git push`.

#### 5. **If you want to abort the merge:**
If you prefer to discard the merge and return to the state before the merge started, you can abort the merge:

git merge --abort

This will restore the branch to the state it was in before the merge started. After aborting the merge, you can proceed with other actions, such as pulling or rebasing.

### After resolving the merge:
Once the merge is completed or aborted, try running `git pull –rebase` or `git push` again, and you should be able to continue your work without issues.

All conflicts fixed but you are still merging.
(use "git commit" to conclude merge)

Changes to be committed:
modified: bitbucket-pipelines.yml

Changes not staged for commit:
(use "git add …" to update what will be committed)
(use "git restore …" to discard changes in working directory)
modified: vite.config.js

Here’s how to resolve this:

### Steps to complete the merge and synchronize the branches:

#### 1. **Review the current state**:
– You’ve already resolved any merge conflicts, and it looks like you've staged the changes in `bitbucket-pipelines.yml` for commit.
– The file `vite.config.js` has local changes that are not staged for commit yet.

#### 2. **Stage any remaining changes**:
Before you complete the merge, you need to either discard or stage the changes in `vite.config.js`.

– **If you want to keep the changes in `vite.config.js`**, stage them:

git add vite.config.js

– **If you want to discard the changes in `vite.config.js`**, you can restore it to the last committed state:

git restore vite.config.js

#### 3. **Commit the merge**:
After staging all necessary changes (including `bitbucket-pipelines.yml` and `vite.config.js` if desired), commit the merge:

git commit

This will conclude the merge process, and you will have successfully merged the changes from both branches.

#### 4. **Pull and integrate the remote changes (if not done already)**:
You mentioned that your branch has diverged from `origin/master`. If the merge was in response to pulling the remote changes, you're already in the process of integrating them. To make sure you're up to date with the latest from the remote repository, run:

git pull origin master --rebase

This ensures that after the merge commit, your local branch will be rebased on top of the latest remote changes.

#### 5. **Push your changes to the remote repository**:
After completing the merge and ensuring everything is up to date, push your local changes to the remote repository:

git push origin master

### Summary of Commands:
1. Stage remaining changes (if needed):

git add vite.config.js

2. Commit the merge:

git commit

3. Pull remote changes (if not already done):

git pull origin master --rebase

4. Push your changes:

git push origin master

By following these steps, you should be able to conclude the merge, resolve the divergence between your local and remote branches, and successfully push your changes.

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# On branch master
# Your branch and 'origin/master' have diverged,
# and have 1 and 1 different commits each, respectively.
#
# All conflicts fixed but you are still merging.
#
# Changes to be committed:
# modified: bitbucket-pipelines.yml
#
# Changes not staged for commit:
# modified: .gitignore

### Steps to finalize the merge:

#### 1. **Stage the `.gitignore` changes**:
The file `.gitignore` has changes that are not yet staged. To include this file in the commit, you need to stage it:

git add .gitignore

#### 2. **Write a commit message**:
You're currently in the merge commit editor, and Git has opened the editor for you to write a commit message. The default message is something like:

Merge branch 'master' of https://bitbucket.org/tiw1988/shareyourthoughts

You can modify this message if you want to add more context. For example:

Merge remote-tracking branch 'origin/master' into master

Resolved conflicts in bitbucket-pipelines.yml and .gitignore.

Once you’ve written the commit message, **save and close** the editor. If you're using the default text editor (Vim), you can do this by typing:
– Press `Esc`
– Type `:wq` (write and quit)
– Press `Enter`

#### 3. **Complete the merge**:
After closing the editor, Git will finalize the merge and commit the changes. If everything is staged correctly, this should resolve the current merge state.

#### 4. **Push your changes**:
After successfully committing the merge, you can push your changes to the remote repository:

git push origin master

### Summary of Commands:
1. Stage the `.gitignore` changes:

git add .gitignore

2. Write the commit message in the editor and save/close it.
3. Push the changes:

git push origin master

This will conclude the merge and synchronize your local and remote repositories.
