pg_restore in postgres docker container

Question

I am trying to restore database in PostgreSQL docker container using pg_restore from a shellscript that will be called from docker file. I'm 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.

这是从位于主机上的文件中恢复的一种方法：

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

Answer 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"

Answer 3

这个从pg_dump -Fc 'pg_dump_Fc_file' 自定义（压缩）数据库转储中为我工作：

docker exec -i container_name pg_restore -Fc -U admin_username -d database_name < pg_dump_Fc_file

Answer 4

Combine the most voted and Heroku's guide , I came up with this:

docker exec -i mohe-bc_db_1 pg_restore --verbose --clean --no-acl --no-owner -U postgres -d mohe-bc_development < ~/Downloads/de8dc786-b133-4ae2-a040-dcf34f12c3de

mohe-bc_db_1 : pg container name showed by docker ps NAMES column

postgres : pg username

mohe-bc_development : db name

~/Downloads/de8dc786-b133-4ae2-a040-dcf34f12c3de : file path of pg db dump

And it works:

pg_restore: connecting to database for restore
pg_restore: dropping CONSTRAINT webhooks webhooks_pkey
pg_restore: dropping CONSTRAINT schema_migrations schema_migrations_pkey
pg_restore: dropping CONSTRAINT ar_internal_metadata ar_internal_metadata_pkey
pg_restore: dropping DEFAULT webhooks id
pg_restore: dropping SEQUENCE webhooks_id_seq
pg_restore: dropping TABLE webhooks
pg_restore: dropping TABLE schema_migrations
pg_restore: dropping TABLE ar_internal_metadata
pg_restore: creating TABLE "public.ar_internal_metadata"
pg_restore: creating TABLE "public.schema_migrations"
pg_restore: creating TABLE "public.webhooks"
pg_restore: creating SEQUENCE "public.webhooks_id_seq"
pg_restore: creating SEQUENCE OWNED BY "public.webhooks_id_seq"
pg_restore: creating DEFAULT "public.webhooks id"
pg_restore: processing data for table "public.ar_internal_metadata"
pg_restore: processing data for table "public.schema_migrations"
pg_restore: processing data for table "public.webhooks"
pg_restore: executing SEQUENCE SET webhooks_id_seq
pg_restore: creating CONSTRAINT "public.ar_internal_metadata ar_internal_metadata_pkey"
pg_restore: creating CONSTRAINT "public.schema_migrations schema_migrations_pkey"
pg_restore: creating CONSTRAINT "public.webhooks webhooks_pkey"

Another variant in case all the shorter ones don't work:

docker exec -i container_name pg_restore -U db_user --verbose --clean --no-acl --no-owner -h localhost -d db_name < db_backup_file

Also, pay attention to the --format option.

(Adding this just for windows users, < is not supported by powerShell). Under powershell:

Get-Content C:\pathToDumpFolder\Mydump.sql | docker exec -i containername psql -U username -v -d dbname
