To backup a PostgreSQL Docker container::
To dump the database into an SQL text file::
docker exec <container name> pg_dump -U <database user> -Fc -c <database name> > dump_`date +%Y-%m-%d"_"%H-%M-%S`.dump
pg_dump -h <host> -U <database user> -c <database name> -W > `date +%Y-%m-%d"_"%H-%M-%S`.sql
Example::
docker exec mayan-edms-db pg_dump -U mayan -Fc -c mayan > date +%Y-%m-%d"_"%H-%M-%S`.dump
pg_dump -h 127.0.0.1 -U mayan -c mayan -W > `date +%Y-%m-%d"_"%H-%M-%S`.sql
To restore the database from the SQL text file::
psql -h <host> -U <database user> -d <database name> -W -f <sql dump file>
Example::
psql -h 127.0.0.1 -U mayan -d mayan -W -f 2018-06-07_18-10-56.sql
Here is an example of how to perform a backup and a restore of a PostgreSQL
Docker container using a compressed dump file. A dump file is not compatible or
can be used interchangeable with an SQL text file.
To backup a PostgreSQL Docker container::
docker exec <container name> pg_dump -U <database user> -Fc -c <database name> > `date +%Y-%m-%d"_"%H-%M-%S`.dump
Example::
docker exec mayan-edms-db pg_dump -U mayan -Fc -c mayan > `date +%Y-%m-%d"_"%H-%M-%S`.dump
This will produce a compressed dump file with the current date and time as the filename.
