pg_restore in postgres docker container

Question

I am trying to restore database in PostgreSQL docker container using pg_restore from a shellscript taht will be called from docker file .I am getting following error "ERROR: canceling autovacuum task CONTEXT: automatic analyze of table 'tablename'".

DockerFile:

    FROM postgres:9.3
    ENV POSTGRES_USER postgres
    ENV POSTGRES_PASSWORD Abcd1234
    ENV POSTGRES_DB Clarion1
    COPY DB.backup /var/lib/postgresql/backup/DB.backup
    COPY initialize.sh /docker-entrypoint-initdb.d/initialize.sh

initialize.sh

    #!/bin/bash
    set -e
    set -x

    echo "******PostgreSQL initialisation******"
    pg_restore -C -d DB /var/lib/postgresql/backup/DB.backup

Log:

    server started
    CREATE DATABASE
    /docker-entrypoint.sh: running /docker-entrypoint-initdb.d/initialize.sh
    ++ echo '******PostgreSQL initialisation******'
    ++ pg_restore -C -d Clarion1 /var/lib/postgresql/backup/Clarion53.backup
    ******PostgreSQL initialisation******
    ERROR:  canceling autovacuum task

But if I try to restore DB from command prompt in host machine from same backup file , it is working fine.

Solution 1

Here is a way to restore from a file located on the host machine:

docker exec -i container_name pg_restore -U postgres_user -v -d database_name < /dir_backup_outside_container/file_name.tar

Solution 2

I don't think the backup restore can be done during the initialization phase. Start your container and then upload the db.

docker run -d --name mydb mypgimage
docker exec mydb sh -c "pg_restore -C -d DB /var/lib/postgresql/backup/DB.backup"
