go build

How to use

ls

./dbdeployer [-cfg path of db.json] ls

Show all supported DBMSs, such as mysql, mariadb, ...

./dbdeployer [-cfg path of db.json] ls dbms

Show all supported docker images under a DBMS (from old to new).

For example, if you use ls mysql, you will see mysql:5.5.40, mysql:5.5.41, ...

We will collect these images from the official dockerhub (mainly) of each DBMS:

• mysql:

  https://hub.docker.com/_/mysql/tags

  https://hub.docker.com/r/vettadock/mysql-old/tags

• mariadb: todo

• tidb: todo

• oceanbase: todo

run

./dbdeployer [-cfg path of db.json] run dbms imageRepo:imageTag port

Make sure your linux user is in the user group docker, see: https://askubuntu.com/questions/477551/how-can-i-use-docker-without-sudo

1. cat /etc/group | grep docker, if the group docker does not exist, sudo groupadd docker
2. sudo gpasswd -a $USER docker
3. close the old terminal, start a new one, use id to check if your user is in the group docker
4. now you can use docker without sudo.

We will run a docker container named test-port-dbms-imageTag on the specified port, with user root, password 123456.

Note that:

• If the container is running, we will do nothing;
• If the container has exited, we will restart it;
• If the container does not exist, we will create it;
• If there is another running container with the prefix test-port, we will stop it first.
• We will wait for the dbms ready

bisect

./dbdeployer [-cfg path of db.json] bisect dbms oldImageRepo:oldImageTag newImageRepo:newImageTag

Return the middle image between oldImage and newImage.
