Dockerfile - falied in download file and extract

General Discussions
1

Hello guys.

I need my Dockerfile file to download a file and extract it in the “/var/www/html” directory of the container. I tried in several ways and failed. Apparently this happens but then it seems that everything is excluded. I’ve tried with the command RUN wget , RUN curl , ADD, etc. I wanted you to get the file on the internet and extract it, that’s all. I found some examples on the internet but my code has some error that I did not identify. Below are the 2 files (Dockerfile and docker-compose.yml) that I am using to do this. I just put wordpress as an example.

file: Dockerfile

I tried to use the ADD command, including this one in the commented code which I already tried, that line was:

#ADD https://br.wordpress.org/wordpress-5.7-pt_BR.tar.gz /var/www/html/
My problem is that it shows downloading and extracting on the console, however when I access the container (by “docker exec -it wordpress bash” ) and give one in the directory (/var/www/html/) it is empty.

Does anyone know what can it be?
