It's updated timestamp of every file
To avoid this, you can use the `–ignore-times` option with `rsync`, which forces it to send files regardless of their timestamps. Here’s an updated version of your deployment step:
name: Deploy to EC2
on:
push:
branches:
- master # Trigger on push to master branch
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up SSH
env:
PEM_FILE: ${{ secrets.PEM_FILE }} # Store your PEM file content in GitHub secrets
run: |
echo "$PEM_FILE" > key.pem
chmod 600 key.pem
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --ignore-times -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./ $EC2_USER@$EC2_HOST:/var/www/share
rm key.pem # Clean up the PEM file after deployment### Explanation of Changes
– **`–ignore-times`**: This option forces `rsync` to send files regardless of their timestamp, which should prevent the issue of files having updated timestamps post-deployment.
### Additional Suggestions
– **Check Permissions**: Ensure that the user (`EC2_USER`) has the appropriate permissions to write to the `/var/www/share` directory on the EC2 instance.
– **Backup**: Consider adding a backup step before the `rsync` command if you're concerned about overwriting existing files.
– **Dry Run**: You can use the `–dry-run` option with `rsync` to test your deployment without making any actual changes. This is useful for verifying what would happen during a real deployment.
Let me know if you need further adjustments or if there's anything else you'd like to discuss!
Here’s your workflow without the `–ignore-times` option, ensuring only affected files have their timestamps updated:
name: Deploy to EC2
on:
push:
branches:
- master # Trigger on push to master branch
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up SSH
env:
PEM_FILE: ${{ secrets.PEM_FILE }} # Store your PEM file content in GitHub secrets
run: |
echo "$PEM_FILE" > key.pem
chmod 600 key.pem
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./ $EC2_USER@$EC2_HOST:/var/www/share
rm key.pem # Clean up the PEM file after deployment### Key Points
– **`-a` Option**: The `-a` (archive) option ensures that `rsync` preserves file permissions, timestamps, symbolic links, and other file attributes while transferring only the files that have changed.
– **Timestamp Updates**: Only files that have been modified will have their timestamps updated on the destination. Unchanged files will not be transferred or modified.
This setup will efficiently synchronize your local files with those on the EC2 instance, updating only the affected files and their timestamps as needed. If you still see timestamps updating for all files, consider checking the following:
1. **File Modification**: Ensure that there are no inadvertent changes to the files (even whitespace changes) that may cause `rsync` to perceive them as updated.
2. **File Ownership and Permissions**: If file ownership or permissions change, it can trigger an update in `rsync`.
3. **Directory Structure Changes**: Changes in directory structure (like adding or removing files) will also trigger an update for the affected directories.

Then again push to build folder
This operation caused update timestamp of every file
To avoid this issue while still ensuring that your deployment process is efficient, you can consider the following approaches:
### 1. Use `rsync` with `–delete` Option
Instead of deleting the directory before the `rsync` command, you can use the `–delete` option to remove files from the destination that are not present in the source. This way, you can synchronize the contents while preserving timestamps for files that remain unchanged.
Here's an updated version of your deployment step:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 2. Only Sync Changes
If you still want to delete the `build` directory but ensure that only affected files are updated, you could change your approach:
– **Optionally, Archive Old Builds**: Instead of deleting the `build` directory directly, you could rename it or move it to a backup location, then create a new `build` directory. This way, you keep the previous builds intact until the new deployment is verified.
### 3. Use a Build Tool
If you are using a build tool (like Webpack, Vite, etc.) to generate the contents of your `build` folder, you could modify your workflow to only push updated files. For example, you can run the build process first, then only deploy the output files if they have changed.
Here’s a general flow you might consider:
- name: Build Assets
run: |
yarn build # or npm run build, depending on your setup
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### Summary
Using `–delete` with `rsync` allows you to clean up the destination without removing the directory entirely. This approach keeps timestamps updated only for files that change while efficiently syncing your build assets. If you prefer to delete the folder entirely, consider backing it up first or only deploying the changed files.
Let me know if you need further assistance or specific adjustments!
Here are some strategies to minimize timestamp updates in folders other than the intended `build` folder:
### 1. Limit the Scope of `rsync`
Instead of using `rsync` to sync the entire project folder, you can specify exactly which directories to synchronize. This way, you can limit the operation to just the `build` folder:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 2. Use Exclusions
If you need to use `rsync` on a broader scope (e.g., the entire project folder), you can exclude directories or files that you do not want to update. Here’s how you can exclude the `app` folder:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete --exclude='app/' --exclude='other/directory/' -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 3. Archive Instead of Delete
If you're performing a deletion operation that leads to significant changes in file structure, consider archiving the `public/build` directory instead of deleting it outright. This method will preserve the original timestamps for existing files while allowing you to deploy new files.
For example:
- name: Backup current build
run: |
ssh -i key.pem -o StrictHostKeyChecking=no $EC2_USER@$EC2_HOST "mv /var/www/share/public/build /var/www/share/public/build_backup_$(date +%Y%m%d%H%M%S)"
- name: Deploy new build to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 4. Check for Changes
After executing `rsync`, if you notice that timestamps are updated for files you did not intend to change, you might want to investigate if:
– **File Permissions or Ownership**: Changes in file permissions or ownership might cause `rsync` to update the timestamps. Ensure that these attributes remain consistent.
– **Symlinks**: If your application uses symlinks that point to other locations, ensure they are valid and not causing updates inadvertently.
### Summary
To keep your deployment focused and minimize unnecessary timestamp updates:
– Limit the scope of `rsync` to only necessary directories or files.
– Use the `–exclude` option to prevent updates in directories that should remain unchanged.
– Consider archiving existing files instead of deleting them to maintain file history and timestamps.
By applying these techniques, you can effectively manage your deployment process while preserving the integrity of your existing files. If you need further guidance or additional modifications, feel free to ask!
### Steps to Achieve This
1. **Avoid Deleting the Whole Directory**: Instead of deleting the entire `public/build` directory, you can use `rsync` to sync the `build` folder without removing it. This way, `rsync` will only update the timestamps of the files that are actually different between your local build and the server.
2. **Use the Correct `rsync` Options**: Ensure you are using `rsync` with the appropriate flags to sync files based on their changes.
### Example Workflow
Here’s how you can structure your GitHub Actions workflow to achieve this:
name: Deploy to EC2
on:
push:
branches:
- master # Trigger on push to master branch
jobs:
deploy:
runs-on: ubuntu-latest
steps:
- name: Checkout code
uses: actions/checkout@v2
- name: Set up SSH
env:
PEM_FILE: ${{ secrets.PEM_FILE }} # Store your PEM file content in GitHub secrets
run: |
echo "$PEM_FILE" > key.pem
chmod 600 key.pem
- name: Build Assets
run: |
yarn build # or npm run build, depending on your setup
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete --ignore-existing -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### Explanation of Options
– **`-a`**: Archive mode, which preserves permissions and timestamps.
– **`-v`**: Verbose output.
– **`-z`**: Compress file data during the transfer.
– **`–delete`**: Deletes files on the destination that are not present in the source directory.
– **`–ignore-existing`**: Prevents updating files that already exist on the server, which means only new files will be transferred, thus not affecting timestamps of unchanged files.
### Important Considerations
– **Directory Structure**: By not deleting the whole `public/build` directory, only the files that have changed or are new will be transferred, thus updating their timestamps.
– **Backup Previous Builds**: If you're worried about losing files, consider backing up the `build` directory before syncing or removing old builds as necessary.
This approach should help you maintain the timestamp integrity on your server while ensuring that only files that have changed get updated. Let me know if you need any more assistance or adjustments!
### 1. Check the Build Process
Ensure that your build process (e.g., `yarn build` or `npm run build`) is not causing unnecessary modifications to the files, which would lead `rsync` to treat them as new files. Sometimes, even minor changes in the output files (e.g., whitespace changes, comments, etc.) can cause timestamps to update.
### 2. Use `rsync` with Proper Options
You can use `rsync` with the `-u` (update) option, which skips files that are newer on the destination. Here’s how you can adjust your deployment command:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avzu --delete -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 3. Exclude Unchanged Files
If you notice certain files or directories that should not be updated, you can exclude them from the `rsync` operation:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete --exclude='app/' --exclude='other-directory/' -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 4. Preserve Timestamps
You can ensure that timestamps are preserved during the `rsync` operation by adding the `–times` option:
- name: Deploy to EC2
env:
EC2_USER: ${{ secrets.EC2_USER }} # Store your EC2 username in GitHub secrets
EC2_HOST: ${{ secrets.EC2_HOST }} # Store your EC2 host in GitHub secrets
run: |
rsync -avz --delete --times -e "ssh -i key.pem -o StrictHostKeyChecking=no" ./build/ $EC2_USER@$EC2_HOST:/var/www/share/public/build
rm key.pem # Clean up the PEM file after deployment### 5. Ensure File Changes Are Intentional
Check your local build files to ensure that they are not being unintentionally modified (e.g., by development tools that may alter them). Run a `diff` between your local `build` directory and the remote `public/build` directory to confirm what is actually different.
### 6. Analyze the `rsync` Output
Run the `rsync` command with increased verbosity (add an additional `-v` for even more detailed output, e.g., `-vv`) to see which files are being transferred and why. This can help identify what is causing the timestamps to update.
### Conclusion
If `rsync` still updates the timestamps of all files, you may need to further investigate the build process or how files are generated and modified. The combination of using the `-u` (update) option, checking for unintended modifications, and using excludes should help limit timestamp updates to only those files that have actually changed.
