First installed podman-compose then created docker file with name docker-compose.yml :<\/p>\n\n\n\n

version: '3.1'\r\n\r\nservices:\r\n\r\n  wordpress:\r\n    image: wordpress1\n    restart: always\r\n    ports:\r\n      - 8080:80\r\n    environment:\r\n      WORDPRESS_DB_HOST: db\n      WORDPRESS_DB_USER: mydbuser\n      WORDPRESS_DB_PASSWORD: mydbpassword\n      WORDPRESS_DB_NAME: mydb\r\n    volumes:\r\n      - wordpress:\/var\/www\/html\r\n      - logs:\/var\/log\/apache2\r\n\r\n  db:\r\n    image: wordpress1db\r\n    restart: always\r\n    environment:\r\n      MYSQL_DATABASE: mydb\n      MYSQL_USER: mydbuser\n      MYSQL_PASSWORD: mydbpassword\r\n      MYSQL_RANDOM_ROOT_PASSWORD: '1'\r\n    volumes:\r\n      - db:\/var\/lib\/mysql\r\n\r\nvolumes:\r\n  wordpress:\r\n  db:\r\n  logs:\r\n<\/code><\/pre>\n\n\n\n
now run :<\/p>\n\n\n\n
podman-compose up -d<\/code><\/pre>\n\n\n\n
It will create containers and run webserver at 8080 port.<\/p>\n\n\n\n
to stop and remove the containers run <\/p>\n\n\n\n
podman-compose down<\/code><\/pre>\n\n\n\n
The docker file will create containers for webserver from image wordpress1 and container for database server from image wordpress1db, please check and update image name incase of any problem. Also you can commit after any change to webserver \/ mysql configuration to create another image locally.<\/p>\n\n\n\n
The running containers will share storage outside the docker for mysql database files(\/var\/lib\/mysql) in named space db and website (\/var\/www\/html) at named space wordpress.  These named spaces can be looked by running:<\/p>\n\n\n\n
# podman volume ls\n\nDRIVER      VOLUME NAME\r\nlocal       fcab36796140245f735851f808b193c38e4771143db12ead1c59ce2b5fa3177e\r\nlocal       WordPress_db\r\nlocal       WordPress_logs\r\nlocal       WordPress_wordpress\r\n<\/code><\/pre>\n\n\n\n
now run following to find out the actual location of the volumes<\/p>\n\n\n\n
# podman volume inspect WordPress_db WordPress_wordpress\n[\r\n    {\r\n        \"Name\": \"WordPress_db\",\r\n        \"Driver\": \"local\",\r\n        \"Mountpoint\": \"\/var\/lib\/containers\/storage\/volumes\/WordPress_db\/_data\",\r\n        \"CreatedAt\": \"2022-01-31T18:54:23.157971622+05:30\",\r\n        \"Labels\": {\r\n            \"io.podman.compose.project\": \"WordPress\"\r\n        },\r\n        \"Scope\": \"local\",\r\n        \"Options\": {}\r\n    },\r\n    {\r\n        \"Name\": \"WordPress_wordpress\",\r\n        \"Driver\": \"local\",\r\n        \"Mountpoint\": \"\/var\/lib\/containers\/storage\/volumes\/WordPress_wordpress\/_data\",\r\n        \"CreatedAt\": \"2022-01-31T18:54:19.661705064+05:30\",\r\n        \"Labels\": {\r\n            \"io.podman.compose.project\": \"WordPress\"\r\n        },\r\n        \"Scope\": \"local\",\r\n        \"Options\": {}\r\n    }\r\n]\r\n<\/code><\/pre>\n\n\n\n
You can add\/modify webserver files located at \/var\/lib\/containers\/storage\/volumes\/WordPress_wordpress\/_data<\/p>\n\n\n\n
To login to any of the containers above first findout the names of containers by running<\/p>\n\n\n\n

the last word in each line is the name i.e.  WordPress_wordpress_1 and WordPress_db_1 are the container names. Now to login to wordpress (webserver) type the following<\/p>\n\n\n\n
