export S3_ACCESS_KEY=your-s3-key
export S3_SECRET_KEY=your-s3-secret
export S3_ENDPOINT=https://s3.<region>.amazonaws.com

# Stack deployment (Swarm-only)
ptctools docker stack deploy -n mystack -f compose.yaml

# Secret management (Swarm-only)
echo "postgresql://user:pass@db:5432/mydb" | ptctools docker secret create db_dsn
ptctools docker secret create -f /path/to/secret.txt my_secret
ptctools docker secret create -v "secret-value" my_secret

# Config management (Swarm-only)
ptctools docker config set -n my-config -d "config content"
ptctools docker config set -n nginx.conf -f ./nginx.conf
ptctools docker config set -n my-config -d "new content" --force
ptctools docker config list
ptctools docker config get -n my-config
ptctools docker config delete -n my-config

# Volume backup/restore (uses Duplicati)
ptctools docker volume backup -v vol1,vol2 -o s3://mybucket
ptctools docker volume restore -i s3://mybucket/vol1  # volume name derived from URI path
ptctools docker volume restore -v vol1 -i s3://mybucket/vol1  # explicit volume name

# Volume copy (raw copy using mc/busybox)
ptctools docker volume cp source dest                         # volume to volume
ptctools docker volume cp s3://mybucket/path dest              # S3 to volume
ptctools docker volume cp source s3://mybucket/path            # volume to S3

# Volume management
ptctools docker volume rm myvolume                             # remove volume (with confirmation)
ptctools docker volume rm -y myvolume                          # remove without confirmation
ptctools docker volume rename old_name new_name                # rename volume (copy + delete)

# Database backup/restore (uses minio/mc for S3)
ptctools docker db backup -c container_id -v db_data \
  --db-user postgres --db-name mydb -o backup.sql.gz
ptctools docker db backup -c container_id -v db_data \
  --db-user postgres --db-name mydb -o s3://mybucket/backups/db.sql.gz

ptctools docker db restore -c container_id -v db_data \
  --db-user postgres --db-name mydb -i backup.sql.gz
ptctools docker db restore -c container_id -v db_data \
  --db-user postgres --db-name mydb -i s3://mybucket/backups/db.sql.gz

# Clean up exited containers and unused images
ptctools docker clean
ptctools docker clean -y  # skip confirmation

# Override PORTAINER_URL with -u flag
ptctools docker secret create -u https://other.portainer.com -f dsn.txt my_secret

# Utils - local Duplicati operations (no Portainer needed)
ptctools utils backup --input ./data --output s3://backups/mydata
ptctools utils restore --input s3://backups/mydata --output ./restored

Commands

ptctools docker stack deploy

Deploy or update a Docker Swarm stack in Portainer.

ptctools docker secret create

Create a Docker Swarm secret. Value can be provided via stdin, file, or command-line argument.

ptctools docker config set/get/list/delete

Manage Docker Swarm configs via Portainer API.

ptctools docker volume backup/restore

• backup: Backup multiple Docker volumes (comma-separated) to S3 using Duplicati container.
• restore: Restore a single Docker volume from S3. Volume name can be specified via --volume or derived from the input URI path.

ptctools docker volume cp

Copy data between volumes and S3 (raw file copy).

• volume to volume: Uses busybox with cp -a
• S3 to volume: Uses minio/mc to download files
• volume to S3: Uses minio/mc to upload files

ptctools docker volume rm

Remove a Docker volume. Use -y to skip confirmation, -f to force removal.

ptctools docker volume rename

Rename a volume by copying data to a new volume and deleting the original.

ptctools docker db backup/restore

Backup/restore PostgreSQL database. Supports both local files and S3 URIs.

• Uses pg_dump/psql for database operations
• Uses minio/mc container for S3 transfers

ptctools docker clean

Remove all exited containers and unused (dangling) images. Use -y to skip confirmation.

ptctools utils backup/restore

Local backup/restore operations using Duplicati CLI (docker or local). Does not require Portainer.

Releasing

The Release GitHub Actions workflow creates a new stable release from main. Run it from the Actions tab and provide a canonical version in X.Y.Z format (without leading zeroes), such as 0.2.2. The workflow:

1. Requires the requested version to be greater than the current package version.
2. Updates pyproject.toml, uv.lock, and src/ptctools/__init__.py.
3. Runs the test suite and builds the wheel and source distribution.
4. Commits the version change to main and creates an annotated vX.Y.Z tag.
5. Creates a GitHub Release with generated notes and both distribution files.
6. Publishes the same distribution files to PyPI through Trusted Publishing.

The workflow uses the repository GITHUB_TOKEN for GitHub and an ephemeral OIDC token for PyPI; no additional release secret is required. The PyPI Trusted Publisher must authorize repository tamntlib/ptctools and workflow release.yml, with environment pypi. A failed test, invalid version, existing tag, or distribution check stops the release before the commit and tag are pushed.
