Chapter 3. Standalone upgrade

Procedure

1. Stop the Red Hat Quay container by entering the following command:

   $ sudo podman stop <quay_container_name>

2. Stop the Clair container by running the following command:

   $ sudo podman stop <clair_container_id>

3. Run the following Podman process from SCLOrg’s Data Migration procedure, which allows for data migration from a remote PostgreSQL server:

   $ sudo podman run -d --name <clair_migration_postgresql_database> 1
     -e POSTGRESQL_MIGRATION_REMOTE_HOST=<container_ip_address> \ 2
     -e POSTGRESQL_MIGRATION_ADMIN_PASSWORD=remoteAdminP@ssword \
     -v </host/data/directory:/var/lib/pgsql/data:Z> \ 3
     [ OPTIONAL_CONFIGURATION_VARIABLES ]
     registry.redhat.io/rhel8/postgresql-15

   1

   Insert a name for your Clair PostgreSQL 15 migration database.

   2

   Your new Clair PostgreSQL 15 database container IP address. Can obtained by running the following command: sudo podman inspect -f "{{.NetworkSettings.IPAddress}}" postgresql-quay.

   3

   You must specify a different volume mount point than the one from your initial Clair PostgreSQL 13 deployment, and modify the access control lists for said directory. For example:

   $ mkdir -p /host/data/clair-postgresql15-directory

   $ setfacl -m u:26:-wx /host/data/clair-postgresql15-directory

   This prevents data from being overwritten by the new container.

4. Stop the Clair PostgreSQL 13 container:

   $ sudo podman stop <clair_postgresql13_container_name>

5. After completing the PostgreSQL migration, run the Clair PostgreSQL 15 container, using the new data volume mount from Step 3, for example, </host/data/clair-postgresql15-directory:/var/lib/postgresql/data>:

   $ sudo podman run -d --rm --name <postgresql15-clairv4> \
     -e POSTGRESQL_USER=<clair_username> \
     -e POSTGRESQL_PASSWORD=<clair_password> \
    	-e POSTGRESQL_DATABASE=<clair_database_name> \
     -e POSTGRESQL_ADMIN_PASSWORD=<admin_password> \
     -p 5433:5432 \
     -v </host/data/clair-postgresql15-directory:/var/lib/postgresql/data:Z> \
       registry.redhat.io/rhel8/postgresql-15

6. Start the Red Hat Quay container by entering the following command:

   $ sudo podman run -d --rm -p 80:8080 -p 443:8443 --name=quay \
   -v /home/<quay_user>/quay-poc/config:/conf/stack:Z \
   -v /home/<quay_user>/quay-poc/storage:/datastorage:Z \
   {productrepo}/{quayimage}:{productminv}

7. Start the Clair container by entering the following command:

   $ sudo podman run -d --name clairv4 \
   -p 8081:8081 -p 8088:8088 \
   -e CLAIR_CONF=/clair/config.yaml \
   -e CLAIR_MODE=combo \
   registry.redhat.io/quay/clair-rhel8:{productminv}
