Container Deployment

pgAdmin can be deployed in a container using the image at:

PostgreSQL Utilities

The PostgreSQL utilities pg_dump, pg_dumpall, pg_restore and psql are included in the container to allow backups to be created and restored and other maintenance functions to be executed. Multiple versions are included in the following directories to allow use with different versions of the database server:

  • PostgreSQL 9.4: /usr/local/pgsql-9.4

  • PostgreSQL 9.5: /usr/local/pgsql-9.5

  • PostgreSQL 9.6: /usr/local/pgsql-9.6

  • PostgreSQL 10: /usr/local/pgsql-10

  • PostgreSQL 11: /usr/local/pgsql-11

The most recent version of the utilities is used by default; this may be changed in the Preferences Dialog.

Environment Variables

The container will accept the following variables at startup:


This is the email address used when setting up the initial administrator account to login to pgAdmin. This variable is required and must be set at launch time.


This is the password used when setting up the initial administrator account to login to pgAdmin. This variable is required and must be set at launch time.


Default: <null>

If left un-set, the container will listen on port 80 for connections in plain text. If set to any value, the container will listen on port 443 for TLS connections.

When TLS is enabled, a certificate and key must be provided. Typically these should be stored on the host file system and mounted from the container. The expected paths are /certs/server.crt and /certs/server.key


Default: [::]

Specify the local address that the servers listens on. The default should work for most users - in IPv4-only environments, this may need to be set to


Default: 80 or 443 (if TLS is enabled)

Allows the port that the server listens on to be set to a specific value rather than using the default.


Default: /pgadmin4/servers.json

Override the default file path for the server definition list. See the /pgadmin4/servers.json mapped file below for more information.


Default: 25

Adjust the number of threads the Gunicorn server uses to handle incoming requests. This should typically be left as-is, except in highly loaded systems where it may be increased.

Mapped Files and Directories

The following files or directories can be mapped from the container onto the host machine to allow configuration to be customised and shared between instances:


This is the working directory in which pgAdmin stores session data, user files, configuration files, and it’s configuration database. Mapping this directory onto the host machine gives you an easy way to maintain configuration between invocations of the container.


This file can be used to override configuration settings in pgAdmin. Settings found in can be overridden with deployment specific values if required.


If this file is mapped, server definitions found in it will be loaded at launch time. This allows connection information to be pre-loaded into the instance of pgAdmin in the container. Note that server definitions are only loaded on first launch, i.e. when the configuration database is created, and not on subsequent launches using the same configuration database.


If TLS is enabled, this file will be used as the servers TLS certificate.


If TLS is enabled, this file will be used as the key file for the servers TLS certificate.


Run a simple container over port 80:

docker pull dpage/pgadmin4
docker run -p 80:80 \
    -e "" \
    -d dpage/pgadmin4

Run a TLS secured container using a shared config/storage directory in /private/var/lib/pgadmin on the host, and servers pre-loaded from /tmp/servers.json on the host:

docker pull dpage/pgadmin4
docker run -p 443:443 \
    -v "/private/var/lib/pgadmin:/var/lib/pgadmin" \
    -v "/path/to/certificate.cert:/certs/server.cert" \
    -v "/path/to/certificate.key:/certs/server.key" \
    -v "/tmp/servers.json:/servers.json" \
    -e "" \
    -e "PGADMIN_ENABLE_TLS=True" \
    -d dpage/pgadmin4
