Full Description

Table of Contents

Installation

docker pull romeoz/docker-sphinxsearch

Alternately you can build the image yourself.

git clone https://github.com/romeoz/docker-sphinxsearch.git
cd docker-sphinxsearch
docker build -t="$USER/sphinxsearch" .

Quick Start

Use one of two ways:

1) Usage Docker Compose

curl -L https://github.com/romeoz/docker-sphinxsearch/raw/master/docker-compose.yml > docker-compose.yml
docker-compose up -d

2) Step by step.

Run the mysql image:

docker run --name db -d \
  -e 'MYSQL_USER=admin' -e 'MYSQL_PASS=pass' -e 'MYSQL_CACHE_ENABLED=true' \
  romeoz/docker-mysql

Recommended way (official). Sphinx own implementation of MySQL network protocol (using a small SQL subset called SphinxQL).

Run the sphinx image:

docker run --name sphinx -d \
  --link db:db \
  romeoz/docker-sphinxsearch

Examples

####Sphinx + MySQL

Run the mysql image with with the creation of database db_test:

docker run --name db -d \
  -e 'MYSQL_USER=admin' -e 'MYSQL_PASS=pass' -e 'MYSQL_CACHE_ENABLED=true' \
  -e 'DB_NAME=db_test' \
  romeoz/docker-mysql

Creating table items and records:

docker exec -it db \
  mysql -uroot -e 'CREATE TABLE db_test.items (id INT NOT NULL AUTO_INCREMENT, content TEXT, PRIMARY KEY(id)) ENGINE = INNODB;'

docker exec -it db \
  mysql -uroot -e 'INSERT INTO db_test.items (content) VALUES ("about dog"),("about cat");'

Run the sphinx image + indexing database:

docker run --name sphinx -d \
  --link db:db \
  -e "SPHINX_MODE=indexing" \
  romeoz/docker-sphinxsearch

Searching records:

host=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' sphinx);
docker exec -it db \
  mysql -P9306 -h${host} -e "SELECT * FROM items_index WHERE MATCH('cat');"

####Sphinx + PostgreSQL

You can using other source type, for example PostgreSQL. If you want to use the SphinxQL, there is no need to install the MySQL server.
It helps to have the mysql-common package and mysql-client (if you need a CLI).

Run the postgresql image with with the creation of database db_test:

docker run --name db-test -d \
  -e 'DB_NAME=db_test' -e 'DB_USER=admin' -e 'DB_PASS=pass' \
  romeoz/docker-postgresql

Creating table items and records:

docker exec -it db-test sudo -u postgres psql db_test \
  -c "CREATE TABLE items (id SERIAL, content TEXT);"
docker exec -it db-test sudo -u postgres psql db_test \
  -c "GRANT SELECT ON ALL SEQUENCES IN SCHEMA public TO admin; GRANT SELECT ON ALL TABLES IN SCHEMA public TO admin;"
docker exec -it db-test sudo -u postgres psql db_test \
  -c "INSERT INTO items (content) VALUES ('about dog'),('about cat');"

Run the sphinx image + indexing database:

docker run --name sphinx -d \
  --link db:db \
  -e "SPHINX_MODE=indexing" -e "SPHINX_CONF=/etc/sphinxsearch/sphinx_pgsql.conf" \
  romeoz/docker-sphinxsearch

Install MySQL Client:

docker exec -it sphinx bash -c 'apt-get update && apt-get install -y mysql-client && rm -rf /var/lib/apt/lists/*'

Searching records:

docker exec -it sphinx \
  mysql -P9306 -h127.0.0.1 -e "SELECT * FROM items_index WHERE MATCH('cat');"

Persistence

For data persistence a volume should be mounted at /var/lib/sphinxsearch/data.

The updated run command looks like this.

docker run --name sphinx -d \
  -v /host/to/path/data:/var/lib/sphinxsearch/data \
  romeoz/docker-sphinxsearch

This will make sure that the data stored in the index is not lost when the image is stopped and started again.

Backup of a indexes

If you are using RT index, then first we need to flush indexes FLUSH RTINDEX:

host=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' sphinx)
docker exec -it db mysql -P9306 -h${host} -e "FLUSH RTINDEX some_rtindex"

Next, create a temporary container for backup:

docker run -it --rm \ 
  --volumes-from sphinx \
  -e 'SPHINX_MODE=backup' \
  -v /host/to/path/backup:/tmp/backup \
  romeoz/docker-sphinxsearch

Archive will be available in the /host/to/path/backup.

Algorithm: one backup per week (total 4), one backup per month (total 12) and the last backup. Example: backup.last.tar.gz, backup.1.tar.gz and /backup.dec.tar.gz.

You can disable the rotation by using env SPHINX_ROTATE_BACKUP=false.

Checking backup

Check-data is the name of index INDEX_NAME.

docker run -it --rm \  
  -e 'SPHINX_CHECK=default' -e 'INDEX_NAME=items_index' \
  -v /host/to/path/backup:/tmp/backup  \
  romeoz/docker-sphinxsearch

Default used the /tmp/backup/backup.last.tar.gz.

Restore from backup

docker run --name sphinx-restore -d \
  --link db:db \
  -e 'SPHINX_RESTORE=default' \
  -v /host/to/path/backup:/tmp/backup  \
  romeoz/docker-sphinxsearch

Environment variables

SPHINX_MODE: Set a specific mode. Takes on the value backup or indexing.

SPHINX_BACKUP_DIR: Set a specific backup directory (default "/tmp/backup").

SPHINX_BACKUP_FILENAME: Set a specific filename backup (default "backup.last.tar.gz").

SPHINX_CHECK: Defines name of backup to indextool --check. Note that the backup must be inside the container, so you may need to mount them. You can specify as default that is equivalent to the /tmp/backup/backup.tar.gz.

SPHINX_RESTORE: Defines name of backup to initialize the demon searchd. Note that the backup must be inside the container, so you may need to mount them. You can specify as default that is equivalent to the /tmp/backup/backup.last.tar.gz.

SPHINX_ROTATE_BACKUP: Determines whether to use the rotation of backups (default "true").

Logging

All the logs are forwarded to stdout and sterr. You have use the command docker logs.

docker logs sphinx

####Split the logs

You can then simply split the stdout & stderr of the container by piping the separate streams and send them to files:

docker logs sphinx > stdout.log 2>stderr.log
cat stdout.log
cat stderr.log

or split stdout and error to host stdout:

docker logs sphinx > -
docker logs sphinx 2> -

####Rotate logs

Create the file /etc/logrotate.d/docker-containers with the following text inside:

/var/lib/docker/containers/*/*.log {
    rotate 31
    daily
    nocompress
    missingok
    notifempty
    copytruncate
}

Optionally, you can replace nocompress to compress and change the number of days.
