How to Clear the Cache for FTP Updates on NuvemShop?

Gustavo Lima — Sun, 09 Feb 2025 16:14:25 +0000

This past weekend, I needed to perform maintenance on a website hosted on NuvemShop, a platform quite popular in Brazil.

The problem? I edited the files via FTP, but the changes took forever to reflect on the site. I tried everything: Cmd + Shift + R, disabling the cache in Google Chrome DevTools, using various headers with ModHeader... and nothing worked. I searched a lot but couldn’t find a direct solution.

Until I had an idea 💡 and discovered a simple way to fix it!

✅ Step-by-step to Clear NuvemShop’s Cache

1️⃣ Go to the NuvemShop admin panel:

My NuvemShop » Edit Current Layout » Advanced CSS Editing

2️⃣ Inside the CSS box, add any text, like (remove this after finish your work):

   //test

3️⃣ Click on "Test CSS", and then click "Publish Changes"

This will force the cache to clear, and your FTP changes will appear instantly! 🎉

I hope this tip helps! If anyone knows an even simpler method, feel free to share in the comments.

AWS EKS - Auth error or Forbidden access

Gustavo Lima — Sun, 25 Aug 2024 16:24:43 +0000

If you're trying to deploy Kubernetes on AWS EKS and encountering authentication errors like these:

Error from server (Forbidden): error when retrieving current configuration of:
Resource: "/v1, Resource=secrets", GroupVersionKind: "/v1, Kind=Secret"
Name: "YOUR_SECRET_NAME", Namespace: "YOUR_NAMESPACE_NAME"
from server for: "STDIN": secrets "YOUR_SECRET_NAME" is forbidden: User "arn:aws:iam::***:user/YOUR_IAM_AWS_USERNAME" cannot get resource "secrets" in API group "" in the namespace "YOUR_NAMESPACE_NAME"

error: error validating "deployment.yaml": error validating data: failed to download openapi: the server has asked for the client to provide credentials; if you choose to ignore these errors, turn validation off with --validate=false

You need to configure the policies correctly. To do this, go to the AWS Console and search for IAM. Select the user you are using to deploy, then go to Add permission » Create inline policy. On the next page, click on JSON, delete everything, and paste the policy below:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "ecr:GetAuthorizationToken",
        "ecr:BatchCheckLayerAvailability",
        "ecr:GetDownloadUrlForLayer",
        "ecr:BatchGetImage",
        "ecr:PutImage",
        "ecr:InitiateLayerUpload",
        "ecr:UploadLayerPart",
        "ecr:CompleteLayerUpload"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "secretsmanager:GetSecretValue"
      ],
      "Resource": "*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "eks:DescribeCluster",
        "eks:ListClusters",
        "eks:DescribeNodegroup",
        "eks:DescribeFargateProfile",
        "ec2:DescribeSubnets",
        "ec2:DescribeRouteTables",
        "ec2:DescribeSecurityGroups"
      ],
      "Resource": "*"
    }
  ]
}

The first block allows ECR access, the second grants access to Secrets Manager, and the last one covers EKS. If you don't need some of them, feel free to remove.

Click Next, give the policy a name, e.g., GitHubActionsDeploy, and then click Save changes.

That's it! With this policy, you will grant only the necessary permissions to deploy a pod on EKS.

Laravel: vendor/bin/sail: No such file or directory

Gustavo Lima — Mon, 31 Jul 2023 16:08:00 +0000

I got this error when clone an existing project from my own repository and tried to bring back with sail up:

sail up
sh: vendor/bin/sail: No such file or directory

And after that I realize that obviously I can't do that because I don't have composer dependencies installed.

So, if you don't want to use the local PHP or don't have it, you can use the following command to run a docker container with the right PHP version to install Composer dependencies.

Run it inside you root project folder:

docker run --rm \
    -u "$(id -u):$(id -g)" \
    -v $(pwd):/var/www/html \
    -w /var/www/html \
    laravelsail/php81-composer:latest \
    composer install --ignore-platform-reqs

Done! Now you can use sail up without any problem.

Disabling ONLY_FULL_GROUP_BY on MySQL docker Laravel Sail

Gustavo Lima — Sun, 20 Nov 2022 12:58:55 +0000

When you get this error:
Error Code: 1055. Expression #11 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'YOUR_COLUMN_NAME_HERE' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

Just put on your docker-compose.yml the follow command on mysql container:

        command:
            --sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION

It will look like this:

    mysql:
        image: 'mysql/mysql-server:8.0'
        ports:
            - '${FORWARD_DB_PORT:-3306}:3306'
        environment:
            MYSQL_ROOT_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ROOT_HOST: "%"
            MYSQL_DATABASE: '${DB_DATABASE}'
            MYSQL_USER: '${DB_USERNAME}'
            MYSQL_PASSWORD: '${DB_PASSWORD}'
            MYSQL_ALLOW_EMPTY_PASSWORD: 1
        command:
            --sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_ENGINE_SUBSTITUTION
        volumes:
            - 'sail-mysql:/var/lib/mysql'
            - './vendor/laravel/sail/database/mysql/create-testing-database.sh:/docker-entrypoint-initdb.d/10-create-testing-database.sh'
        networks:
            - sail
        healthcheck:
            test: ["CMD", "mysqladmin", "ping", "-p${DB_PASSWORD}"]
            retries: 3
            timeout: 5s

Restart and test again :D

RUN apk add --update --no-cache build-base python3-dev python3 libffi-dev libressl-dev bash git gettext curl \
 && curl -O https://bootstrap.pypa.io/get-pip.py \
 && python3 get-pip.py \
