Podman on Linux

In this guide, you will deploy MyEMS with Podman on Linux.

Prerequisites

Installed podman, npm on the host.
Installed MySQL server.
The MySQL database can be connected from the host on which the Podman Engine runs.

caution

It is recommended to use root privileges to execute podman commands.
After installing podman, use the command systemctl status podman-restart.service to check if the containers are configured for automatic startup and policy. If Unit not found is displayed, it means that the container cannot be automatic startup.

Step 1 Database

See Database

Step 2 myems-api

In this section, you will install myems-api on Podman.

Copy source code to root directory

cp -r myems/myems-api /
cd /myems-api

Create .env file based on example.env file

caution

Manually replace ~~127.0.0.1~~ with real HOST IP address.

cp example.env .env

Build Image from Source Code

podman build -t myems/myems-api .

To build for multiple platforms and not only for the architecture and operating system that the user invoking the build happens to run. You can use buildx and set the --platform flag to specify the target platform for the build output, (for example, linux/amd64, linux/arm64, or darwin/amd64).

podman buildx build --platform=linux/amd64 -t myems/myems-api .

Run a Podman container

On host, create a share upload file folder:

mkdir /myems-upload

Create a container, bind-mount the share folder to the container, and also bind-mount the .env to the container:

podman run -d -p 8000:8000 -v /myems-upload:/var/www/myems-admin/upload -v /myems-api/.env:/code/.env:ro --log-opt max-size=1m --log-opt max-file=2 --restart always --name myems-api myems/myems-api

-d Run container in background and print container ID
-p Publish a container's port(s) to the host, 8000:8000 (Host:Container) binds port 8000 (right) of the container to TCP port 8000 (left) of the host machine.
-v If you use -v or --volume to bind-mount a file or directory that does not yet exist on the Podman host, -v creates the endpoint for you. It is always created as a directory. The ro option, if present, causes the bind mount to be mounted into the container as read-only.
--log-opt max-size=2m The maximum size of the log before it is rolled. A positive integer plus a modifier representing the unit of measure (k, m, or g).
--log-opt max-file=2 The maximum number of log files that can be present. If rolling the logs creates excess files, the oldest file is removed. A positive integer.
--restart Restart policy to apply when a container exits
--name Assign a name to the container

The absolute path before colon is for path on host and that may vary on your system. The absolute path after colon is for path on container and that CANNOT be changed. By passing .env as bind-mount parameter, you can change the configuration values later. If you changed .env file, restart the container to make the change effective.

If you want to immigrate the image to another computer,

Export image to tarball file

podman save --output myems-api.tar myems/myems-api

Copy the tarball file to another computer, and then load image from tarball file

podman load --input .\myems-api.tar

Step 3 myems-admin

In this section, you will install myems-admin on Podman.

Copy source code to root directory

cp -r myems/myems-admin /
cd /myems-admin

caution

Manually replace ~~127.0.0.1:8000~~ in nginx.conf with actual HOST ip and port of myems-api

nano nginx.conf

      proxy_pass http://127.0.0.1:8000/;

Build Image from Source Code

podman build -t myems/myems-admin .

podman buildx build --platform=linux/amd64 -t myems/myems-admin .

Run a Podman container

On host, create a share upload file folder:

mkdir /myems-upload

Create a container, bind-mount the share upload file folder to the container and also bind-mount nginx.conf

podman run -d -p 8001:8001 -v /myems-upload:/var/www/myems-admin/upload -v /myems-admin/nginx.conf:/etc/nginx/nginx.conf:ro --log-opt max-size=1m --log-opt max-file=2 --restart always --name myems-admin myems/myems-admin

-d Run container in background and print container ID
-p Publish a container's port(s) to the host, 8001:8001 (Host:Container) binds port 8001 (right) of the container to TCP port 8001 (left) of the host machine.
-v If you use -v or --volume to bind-mount a file or directory that does not yet exist on the Podman host, -v creates the endpoint for you. It is always created as a directory. The ro option, if present, causes the bind mount to be mounted into the container as read-only.
--log-opt max-size=2m The maximum size of the log before it is rolled. A positive integer plus a modifier representing the unit of measure (k, m, or g).
--log-opt max-file=2 The maximum number of log files that can be present. If rolling the logs creates excess files, the oldest file is removed. A positive integer.
--restart Restart policy to apply when a container exits
--name Assign a name to the container

-d Run container in background and print container ID
-v If you use -v or --volume to bind-mount a file or directory that does not yet exist on the Podman host, -v creates the endpoint for you. It is always created as a directory. The ro option, if present, causes the bind mount to be mounted into the container as read-only.
